  • Low V GS(off) voltage -1.6 to -3.9V
  • Small package size SOT-89 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 25 ºC. 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.
