ProTek Devices, based in Tempe, Arizona USA, is a manufacturer of Transient Voltage Suppression (TVS) products designed specifically for the protection of electronic systems from the destructive effects of Lightning, Electrostatic Discharge (ESD), Nuclear Electromagnetic Pulse (NEMP) and Inductive Switching.  With 25 years of engineering and manufacturing experience, ProTek designs TVS devices that provide application specific protection solutions for any type of electronic system such as, telecommunications, industrial, military and commercial applications.

In 1992, ProTek Devices acquired the Tempe, Arizona operation of General Semiconductor, Inc. (GSI) from the Square D Company.  By acquiring GSI's line of high quality commercial and military TVS assemblies, and developing a wide range of new high performance transient voltage suppression products, ProTek has become a recognized industry leader.  Today, the company's broad and diversified product line ranges from board-level, surface mount arrays; to after-market megawatt systems.

ProTek Devices' major customers are in the industrial, computer, telecommunications and aerospace markets, and its products are sold worldwide both to OEM and Electronic Distributors.

At ProTek Devices, transient voltage protection is our only business.  We utilize the latest technologies in the design and fabrication of our products, bringing together more than two decades of engineering and manufacturing experience to fields of transient and surge protection.

ProTek' acquired the Silica Tek fab in July of 1999.  The fab has the capability of processing 4", 6", 8" and 12" silicon wafers and will be used primarily for new products currently under development at ProTek.  The facility also has complete "thin" film" capability.

The acquisition of the Silica Tek wafer fab aided in the fabrication of new, advanced devices which protect telecommunication systems, network systems, computers and other voltage sensitive electronics from the effects of lightning and Electrostatic Discharge (ESD).

ProTek's highly qualified and accredited staff includes some of the industry's best engineering talent.  Many of our engineers are active members of IEEE, NEMA, JC-13, JC-22 and IEC and other industry associations, and have contributed significantly to the formation of current standards, specifications and electrical codes for surge suppression methodology.

ProTek has pioneered many innovative TVS products which set benchmarks for quality, reliability and performance.  This is due to our in-depth understanding of the transient environment, and the capability to manufacture World Class Quality devices.  In addition, ProTek's ongoing development program is yielding new products designs which meet and exceed today's most demanding requirements for transient voltage protection
