ON Semiconductor (onsemi) distributor & excess inventory

About ON Semiconductor / onsemi

ON Semiconductor Corporation — which rebranded its trade name to lowercase onsemi in 2021 while keeping ON Semiconductor as the legal entity name — is a Phoenix, Arizona-based intelligent power and sensing supplier that was spun off from the Motorola Semiconductor Products Sector in 1999. With roughly 30,000 employees and fabs across the United States, Czech Republic, Japan, South Korea, Malaysia, and the Philippines, onsemi has grown through an unusually aggressive acquisition track: Cherry Semiconductor (2000, PWM controllers), AMI Semiconductor / AMIS (2008, mixed-signal ASICs and structured-ASIC platforms), Catalyst Semiconductor (2008, serial EEPROM and power management), Sanyo Semiconductor (2011, LB/LC discretes and motor drivers), Pulsecore, Aptina Imaging (2014, CMOS image sensors including the automotive AR-series), Fairchild Semiconductor (2016, the largest acquisition — bringing FDS/FQP MOSFETs, NDS/NDT small-signal transistors, NPT/NIS/NLV logic, PowerTrench, ShieldGATE, and the classic 1N/2N diode families), SensL (2018, silicon photomultipliers for LiDAR), Quantenna Communications (2019, Wi-Fi 5/6 SoCs), and GT Advanced Technologies (2021, silicon-carbide boule and wafer production). The current product mix is heavily weighted toward power semiconductors (EliteSiC MOSFETs and SBDs, T-series IGBTs, PowerTrench MOSFETs), automotive (image sensors for ADAS, NCV PMICs, gate drivers, motor control ICs, and LiDAR SiPM arrays), and industrial sensing (PYTHON and Hyperlux image sensors, ambient light, and pressure).

Hybrid Electronics has quoted ON Semiconductor — and every legacy brand rolled into it — since we opened our doors in 1995. We support customers on obsolete Fairchild FDS/FQP/FDP MOSFETs for locked-BOM industrial designs, discontinued Aptina MT9-series image sensors for fielded machine-vision and automotive cameras, legacy Catalyst CAT24C and CAT93C EEPROM for calibration storage and configuration memory, Sanyo LB-series motor drivers for legacy office automation, Motorola-heritage MC1xxx analog for defense and medical BOMs, and allocated EliteSiC MOSFETs, T-series IGBTs, and automotive AR-series image sensors where onsemi's own authorized channel lead times are running 26–52 weeks. When onsemi or a franchised distributor shows zero stock, we source from OEM excess, contract-manufacturer surplus, and traceable secondary channels.

Notable onsemi part numbers we track

Hybrid Electronics quotes and sources the following onsemi and legacy-brand parts across SiC power, IGBT, silicon MOSFET, image sensor, analog, logic, EEPROM, and automotive segments. onsemi uses NTBG/NTHL/NVBG/NVHL for EliteSiC MOSFETs, FFSH for SiC Schottky diodes, NGTB/FGH for IGBTs, FDS/FDP/FQP/FDPF/FDMS for Fairchild PowerTrench MOSFETs, NTMFS/NTP/NVMFS for onsemi ShieldGATE, NCV for AEC-Q100 automotive, AR/MT9/NOIL/NOIP for image sensors, MMBT/NDT/NDS for small-signal, MC74HC/NL27/NLV for logic, MC10EP/MC100EP for LVPECL clock, CAT24C/CAT93C for EEPROM, and MC33xxx/MC34xxx/LM for jellybean analog — contact us for the exact ordering part number, package suffix, and revision you need.

EliteSiC M3S 1700V samples, Hyperlux LP AR0823AT automotive image sensors, PYTHON 300 / 500 / 1300 industrial imagers, SensL C-series and R-series SiPMs for LiDAR, and additional NCV automotive PMICs also quoted on request. Ordering part numbers include tape-and-reel and tube suffixes (T1, T3, G, R2G) — specify packing and date-code range on your RFQ.

onsemi quote & sourcing FAQ

What onsemi products does Hybrid Electronics quote most often?

EliteSiC 1200 V MOSFETs (NTBG, NTHL, NVBG prefixes) for EV and PV inverter builds, Fairchild-legacy PowerTrench and QFET MOSFETs (FDS, FDP, FQP, FDPF) for industrial and consumer power stages, automotive NCV-series PMICs and gate drivers, and AR-series automotive image sensors are our highest-volume onsemi categories. MC-prefix jellybean analog, Catalyst CAT24C EEPROM, and MMBT/1N-series discretes are steady mid-volume sourcing lines for medical, aerospace, and industrial customers.

Can Hybrid Electronics source current-production EliteSiC and Hyperlux parts?

Yes — on an inquiry basis. EliteSiC 1200 V M3S MOSFETs and Hyperlux/AR-series automotive image sensors remain allocated in 2026, with authorized-channel lead times running 26–52 weeks. We quote per-unit on demand against real-time OEM-excess supply and channel partner stock rather than holding inventory. Include your target quantity, package option (TO-247-3, TO-247-4 Kelvin, D2PAK-7L, TOLL for EliteSiC; iBGA-64, iCLGA for AR-series), and required date-code range, and we'll return an availability window and firm quote.

Do you handle legacy Fairchild, Sanyo, Aptina, and Catalyst parts?

Yes — every legacy brand rolled into onsemi is core to what we do. ON Semiconductor acquired Fairchild in 2016 (bringing PowerTrench, QFET, FGH IGBTs, and the classic 1N/2N families), Aptina in 2014 (MT9-series and current AR-series image sensors), Sanyo Semiconductor in 2011 (LB/LC discretes and motor drivers), and both Catalyst and AMI/AMIS in 2008. For designs locked to Fairchild-, Sanyo-, Aptina-, or Catalyst-branded packaging and markings, we source factory-sealed original inventory from OEM excess and traceable secondary channels — not repackaged or remarked parts.

Are your legacy onsemi parts factory sealed and traceable?

Yes when available — most of our OEM-excess and CEM-surplus onsemi, Fairchild, Sanyo, Aptina, and Catalyst stock is factory sealed with original date codes, moisture-barrier bags, and full traceability documentation. For downgraded stock we disclose condition (open box, tested-pull, refurbished) on the quote. Customers needing MSL data, COO, DPAS-rated delivery, AEC-Q100/Q101 grade confirmation, or PPAP-level documentation should note that on the RFQ.

How fast is your onsemi quote turnaround?

Same day for parts in stock — typically within 2 hours during business hours (9am–6pm ET). Sourced quotes on out-of-stock or allocated parts (EliteSiC 1200 V, Hyperlux/AR-series ADAS sensors, T-series IGBTs, SensL SiPMs) return within 24–48 hours with an availability window. Email sales@hybridelectronics.com or call (407) 542-3995 to open an RFQ.

What's the difference between ON Semiconductor and onsemi?

They're the same company. In 2021 the firm rebranded its trade name and logo to lowercase onsemi, but the legal entity name ON Semiconductor Corporation is unchanged — datasheets, purchase orders, and marking codes still use both. We quote either presentation and match customer PN nomenclature exactly on packing lists and COOs.

Is Hybrid Electronics an authorized ON Semiconductor distributor?

No — we're an independent distributor and excess-inventory buyer sourcing from OEM excess, CEM surplus, and traceable secondary channels since 1995. For factory-warranted current-production orders on onsemi, Fairchild, Sanyo, Aptina, or Catalyst parts, work with an onsemi-franchised distributor. For obsolete, allocated, hard-to-find, or urgent line-down parts where authorized channels show zero stock or 40+ week lead times, Hybrid Electronics is a proven independent source.
