The CPC3720 is an N-channel, depletion mode, field
effect transistor (FET) that utilizes IXYS Integrated
Circuits Division’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 our 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
P
, and is available in an SOT-89 package.
As with all MOS devices, the FET structure prevents
thermal runaway and thermal-induced secondary
breakdown.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to the
device. Functional operation of the device at conditions beyond
those indicated in the operational sections of this data sheet is
not implied.
Typical values are characteristic of the device at +25°C, and are
the result of engineering evaluations. They
are provided for information purposes only, and are not part of
the manufacturing testing requirements.
