The CPC3720 is an N-channel, depletion mode, field

effect transistor (FET) that utilizes Clare’s proprietary

third-generation vertical DMOS process. The

third-generation process realizes world class, high

voltage MOSFET performance in an economical

silicon gate process. Our vertical DMOS process

yields a robust device, with high input impedance,

for use in high power applications. The CPC3720

is a highly reliable FET device that has been used

extensively in Clare’s solid state relays for industrial

and telecommunications applications.

This device excels in power applications requiring

low drain-source resistance, particularly in cold

environments such as automotive ignition modules.

The CPC3720 offers a low, 22

 maximum, on-state

resistance at 25ºC.

The CPC3720 has a minimum breakdown voltage

of 350V

As with all MOS devices, the FET structure prevents

thermal runaway and thermal-induced secondary

breakdown.
