CotoMOS® CT139/CS139

The CT139 and CS139 combine Coto quality and economy in an industry standard 6-pin DIP package. The CT139 and CS139 offer industry-leading switching capability in through-hole and surface-mount packages. Both relays can be configured to switch 50mA AC/DC in A-Configuration, 70mA DC in B-Configuration and 90mA in C-Configuration. See our Application Note entitled “How to Increase Your Current Capacity of 6-pin CotoMOS® Solid State MOSFET Relays by up to 100%” for additional details. Relays are ideally suited for Industrial, Battery Management and Test & Measurement Applications where high voltage switching is required.
