The CPC3720C is an N-channel depletion mode field

effect transistor (FET) that utilizes Clare’s proprietary

third generation vertical DMOS process. Third

generation process realizes world class, high voltage

MOSFET performance in an economical silicon gate

process. Our vertical DMOS process yields a robust

device for high power applications with high input

impedance. The CPC3720C 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 CPC3720C offers a low 20 ohm maximum on-

state resistance at 25ºC.

The CPC3720C has a minimum breakdown voltage of

350V and is available in an SOT-89 package. As with

all MOS devices, the FET structure prevents thermal

runaway and thermal-induced secondary breakdown.
