ProTek Devices is a semiconductor manufacturer in Tempe, Arizona specialising in circuit protection. The company began in 1992 when it acquired the Tempe operations of General Semiconductor, Inc. from the Square D Company, taking on that unit's line of commercial and military transient voltage suppression assemblies. It has since developed a broad portfolio of transient voltage suppression and ESD protection products ranging from board-level surface-mount arrays to after-market megawatt module systems. ProTek Devices' parts are used worldwide in consumer, industrial, telecommunications and military equipment requiring surge and transient protection.
