Protek- TVS diode Array-leading semiconductor of high performance TVS protection products




ProTek Devices is a leading semiconductor manufacturer of a wide range of high-performance TVS protection products. With over 25 years of engineering and manufacturing experience, we offer application specific solutions for all electronic equipment/systems.

Industry Leader

Since 1992, ProTek Devices has led the charge in developing innovative circuit protection solutions.


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. 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. In addition, ProTek's ongoing development program is yielding new products designs which meet and exceed today's most demanding requirements.

A typical WAN configuration consists of centralized servers, workstations and peripheral devices. The equipment within this configuration are susceptible to damage caused by ESD, EFT, EMI and secondary lightning threats.

Protection from these threats lies in the individual discrete protection for I/O ports at all equipment levels. Protection can also be provided at the system interconnecting ports. The protection schemes outlined are recommended for low insertion loss, high signal integrity and low noise/crosstalk with increasing bandwidth.

ProTek products provide protection from the effects of ESD/EFT/Surges as defined by IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5.
