About Micross Components

Micross Components, Inc. is a global provider of high-reliability microelectronic products and services for the aerospace, defense, space, medical, industrial, energy, and communications markets. The business has been trading for more than 45 years (dating the group to circa 1979–1980), and its current corporate form was assembled by Behrman Capital, a private equity firm based in New York and San Francisco. Behrman first invested in the Micross platform through its acquisition of Corfin Industries in 2018 via Fund VI, combined Corfin with Micross in 2020, and in February 2022 closed Behrman Capital Micross CF L.P., an approximately $500 million single-asset continuation fund that continues to hold the Micross position today. Vincent M. Buffa, a Behrman Capital operating partner, has served as Chairman and Chief Executive Officer of Micross since February 2020.

Micross runs a multi-site U.S. operational model that supports die and wafer supply, advanced interconnect, custom packaging and assembly, component modification, electrical and environmental test, and mission-critical high-reliability discrete products. Key operating sites include the corporate office in Melville, New York; the die and hi-rel components campus at Apopka / Orlando, Florida (1810 S. Orange Blossom Trail, with an additional 85,000 sq ft facility on S. Blossom Trail); an Advanced Interconnect Technology (AIT) site at 3021 East Cornwallis Rd, Research Triangle Park, North Carolina (CAGE Code 7QZQ8); the San Jose, California HiRel DC-DC converter line acquired from Infineon Technologies in February 2023; and — most directly relevant to MIL-PRF-19500 — the Corpus Christi hi-rel diode foundry and manufacturing operation in Reynosa, Tamaulipas, Mexico. In January 2025 Micross also closed the acquisition of Integra Technologies (Wichita, Kansas and Milpitas, California), a U.S.-domiciled OSAT post-processing provider.

The Corpus Christi diode line has an equally specific origin. In May 2022, Micross announced the acquisition of Semtech Corpus Christi Corporation from Semtech Corporation for approximately $30 million in an all-cash transaction, with roughly 200 plant employees in Reynosa continuing to operate under Micross management. Micross has since described the operation as a near-shored supply-chain asset — the plant sits roughly 4 miles from the U.S. border in a 70,000 sq ft footprint — and, in November 2024, announced a comprehensive modernization program covering new fab equipment, new infrastructure, and new cleanrooms, followed by a grand re-opening in January 2025. Together, these steps anchor Micross's role as an on-shored / near-shored source for JAN-level hermetic discrete diodes.

QPL / QML-19500 status

The Defense Logistics Agency (DLA) Land and Maritime real-time list of qualified sources for MIL-PRF-19500 currently shows Micross under the following active entry:

  • Micross Corpus Christi S.A. de C.V. — CAGE Code SH879. Manufacturer address: Carretera A Matamoros KM 9, Calle Principal B S/N, Edificio 7, Parque Industrial Sur, Reynosa, Tamps, MX. Secondary plant locations of record include PYNMAX Technology Co., Ltd. (wafer fab, Yong'an District, Kaohsiung, Taiwan) and LiteOn Semiconductor Corp. (wafer fab, Ta Wu Lung, Keelung, Taiwan).

The current line inherits the QPL heritage of the former Semtech Corpus Christi hi-rel discrete diode business. Micross has publicly announced that its Corpus Christi facility is qualified to JAN, JANTX, and JANTXV on multiple slash sheets, holds JANS (space-level) qualification on selected families, and is expanding JANS across the /427, /429, /483, and /586 families through a 2025 qualification campaign. The Corpus Christi diode line is one of only a handful of near-shored MIL-PRF-19500 qualified sources for hermetic axial glass discrete diode product, and Micross positions it explicitly as a mitigation for DMSMS (Diminishing Manufacturing Sources and Material Shortages) risk on legacy JAN and JANTX diode families.

Buyers should note that many part numbers currently supplied by Micross Corpus Christi carry legacy Semtech traceability on older date codes, and current-production equivalents are typically flow-cased under Micross's post-2024 modernized process. Micross also holds significant adjacent qualifications elsewhere in the group — most notably MIL-PRF-38534 Class H (hybrid microcircuits) and MIL-PRF-38535 Class Q (monolithic microcircuits) certifications at its Apopka, Florida facility, and AS9100:2016 / ISO 9001:2015 registration on the same site.

MIL-PRF-19500 quality levels — what JAN, JANTX, JANTXV, and JANS actually mean

MIL-PRF-19500 is the U.S. Department of Defense performance specification for hermetically-sealed discrete semiconductor devices — diodes, rectifiers, transistors, thyristors, SCRs, and TVS devices — administered by the DLA Land and Maritime office in Columbus, Ohio (the successor organization to DSCC-VQ). The specification defines a stack of ascending product-assurance levels indicated by the prefix on a part number:

Prefix Level name What it adds Typical use case
JAN Joint Army-Navy Baseline qualification against slash sheet, Group A/B/C conformance Ground defense, ruggedized industrial
JANTX JAN with eXtra Testing Adds 168-hour burn-in and additional 100% electrical screening Airborne, avionics, missile
JANTXV JANTX with Visual inspection Adds 100% pre-cap internal visual inspection Higher-reliability avionics, tactical space
JANS Joint Army-Navy-Space Adds wafer lot acceptance, Group E conformance and full space screening Launch vehicles, satellites, deep space
JANHC / JANKC Chip / die-level Unencapsulated die screening for downstream hybrid assembly MIL-PRF-38534 hybrids, custom modules

On top of the individual part-type qualification (the older Qualified Products List, QPL), the DoD now operates a line-level certification model called the Qualified Manufacturers List (QML), which is the framework Micross Corpus Christi is certified against. For JANS space-level parts, MIL-PRF-19500 further defines Radiation Hardness Assurance (RHA) levels — encoded as a single character (M, D, P, L, R, F, G, or H) that corresponds to Total Ionizing Dose guarantees ranging from 3 krad(Si) at "M" up to 1 Mrad(Si) at "H". Rectifier and diode structures are naturally hard against TID up to roughly 106 – 107 rad(Si) and neutron fluences of order 1014 n/cm2, so MIL-PRF-19500 does not always require an explicit RHA level on JANS diode product; those parts are inherently rad-hard by construction.

Micross Corpus Christi's MIL-PRF-19500 product portfolio

Micross's MIL-PRF-19500 line is centered on hermetic axial-leaded glass discrete diodes — rectifiers, TVS devices, zeners, and Schottky diodes — in DO-204AH and related axial outlines, produced with a Category I metallurgical bond and rated across −65 °C to +175 °C thermal shock. In line with buyer intent, this page lists part families and slash sheets rather than individual JAN part numbers — specific part-number availability is confirmed on quote.

Standard-recovery rectifiers

The MIL-PRF-19500/240 axial-leaded rectifier family — hermetic glass packages, direct drop-in replacements for legacy silicon rectifier diode types — is production-released at Corpus Christi and available with custom screening up to JAN, JANTX, JANTXV, and JANS quality levels. This family is the workhorse legacy-rectifier product that anchors much of the near-shore diode qualification investment.

Higher-current and higher-voltage axial rectifiers

Rectifier families qualified against slash sheets /420, /427, and /429 cover the higher-current axial rectifier space, with Corpus Christi holding public qualification up to JANTXV today and JANS qualification being extended across those families under a 2025 qualification program. The /483 family (announced as JANTXM part types) is similarly on the current release plan.

Fast, ultrafast, and superfast recovery rectifiers

Slash sheets /411 (fast recovery) and /477 (superfast recovery axial and surface-mount packages) round out the recovery-speed portfolio. Categories under this umbrella include standard recovery, high-voltage, fast recovery, and ultrafast / superfast recovery. Micross's Space Grade Hi-Rel Diodes flyer explicitly lists the /411, /420, /427, /429, and /477 rectifier families as part of its MIL-PRF-19500 diode roadmap.

Transient Voltage Suppressors (TVS)

Hermetic TVS devices per slash sheet /516 and adjacent series are part of the Corpus Christi product mix, in both unidirectional and bidirectional configurations for military avionics, ground-vehicle power buses, and space power distribution. Up-screening to JANS is available on selected TVS families.

Zener voltage regulators

Hermetic zener diodes for voltage regulation and precision reference use are part of the modernization plan announced in November 2024, alongside the QPL rectifier and TVS product lines. Custom up-screening to JANTX / JANTXV / JANS levels is available on non-JANS product families as part of the Corpus Christi service offering.

Schottky rectifiers

Silicon Schottky rectifiers under MIL-PRF-19500/586 (axial hermetic packages, including through-hole and MELF surface-mount variants) are on the current qualification and release plan, with JANS levels being extended in the 2025 qualification campaign. These parts serve satellite power distribution, motor drive, and low-loss point-of-load rectification in high-reliability systems.

Unencapsulated die: JANHC and JANKC

In parallel with the axial packaged portfolio, Micross plans to qualify and release bare-die options for its QPL diode families — a natural fit with Micross Group's die and wafer heritage and the Apopka MIL-PRF-38534 hybrid line, which consumes JANHC / JANKC die for downstream hermetic hybrid assemblies.

Manufacturing model and packaging heritage

The Corpus Christi line runs both custom low-rate production and high-volume full-rate production. Product ships from the modernized 70,000 sq ft Reynosa facility, with wafer supply from the two Taiwan wafer-fab plant-locations of record (PYNMAX and LiteOn Semiconductor). Package inventory is dominated by hermetic axial glass outlines (DO-204AH and related) with additional MELF surface-mount styles for the /427, /429, and Schottky families.

Near-shore supply chain and DMSMS mitigation

The Corpus Christi / Reynosa operation is explicitly positioned by Micross as a near-shored reinforcement of the U.S. hi-rel diode supply chain. The plant is roughly four miles from the U.S. border and, following the 2024–2025 modernization program, ships current-production JAN, JANTX, JANTXV, and JANS discrete diode product with the equipment, infrastructure, and cleanrooms rebuilt from the ground up. Micross has described the investment as a direct answer to DMSMS risk on legacy JAN rectifier, TVS, zener, and Schottky families — the same families that historically shipped from a small number of U.S. hi-rel diode fabs, some of which have since exited the market or been rolled into larger portfolios.

The result, for defense-electronics buyers, is a second source for a broad slice of the MIL-PRF-19500 hermetic axial diode catalog — carrying the same slash-sheet flow, the same JAN quality-level ladder, and the same DLA Land and Maritime line-level oversight, from a facility that sits inside the North American manufacturing footprint.

How Hybrid Electronics sources Micross JAN parts

Hybrid Electronics Corporation is a Sanford, Florida-based independent stocking distributor and sourcing agent, founded in 1981 as Knight Electronics. We are not an authorized distributor, agent, licensee, or franchised partner of Micross Components, Inc. What we do is help defense, aerospace, medical, and industrial buyers close JAN-level BOMs when the authorized channel cannot support the exact date code, package variant, slash-sheet revision, or obsolete lot they need.

Legacy JAN diode inventory

Older date codes, legacy Semtech Corpus Christi-era part numbers, and slash-sheet revisions not on Micross's current production plan. We source excess inventory from OEMs, CMs, and long-term storage stocks and can typically provide date-coded traceability documentation.

Allocated current-production JAN parts

JAN, JANTX, JANTXV, and JANS diode part numbers that are actively produced at Corpus Christi but on long lead time or allocation. Send us a shortage list or a full BOM — we will confirm what we can source, in which package, and at what lead time.

Slash-sheet and cross-reference sourcing

Have a MIL-PRF-19500 slash-sheet reference (e.g. /240, /411, /427, /429, /477, /516, /586) but not a settled manufacturer part number? We can quote Micross options and, where useful, cross to equivalent QPL-19500 sources from other qualified manufacturers.
