ProTek Devices’ TVS Components Provide Circuit Protection in Power Supply, AC/DC, and Telecom Systems

Sept. 19, 2017 – ProTek Devices™ has introduced a new series of transient voltage suppressor components (TVS components) with 600 watts peak pulse power per line to provide IEC-grade circuit protection in power supply, AC/DC, and telecommunications systems. The P6SMBxxxA/CA series offers reverse stand-off voltages ranging from 5.8 to 513 volts.

There are 17 components in the P6SMBxxxA/CA series to cover the various voltage offerings. The series is compatible with IEC standards 61000-4-2 (ESD): level 4 – air 15kV, contact 8kV; with 61000-4-4 (EFT): 40A, 5/50ns; and with 61000-4-5 (surge): 8/20 micro second waveform. The TVS components allow bidirectional and unidirectional configuration options. They also provide low leakage current, a strong clamping capability, and a very fast response time. The series is also fully RoHS and REACH compliant and has a flammability rating of UL 94V-0.

Mechanical, Packaging and Availability Information

ProTek Devices offers components from the P6SMBxxxA/CA series as glass passivated chips in a molded JEDEC DO-214AA package. They have an approximate weight of only 0.103 grams. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin – Sn, 100) 260-270 degrees Celsius. The terminal is solder capable, per MIL-STD-750, method 2026.

The P6SMBxxxA/CA series is provided on 12mm tape and reel, per EIA standard 481, in minimum quantities of 3,000.  Pricing information and purchasing details can be had by contacting any authorized distributor, representative, or directly with ProTek Devices. The company’s distributor and representative channels are available worldwide across the USA, Europe, Asia, Latin America and more. Full contact information for all regions can be found at the company website.
