General Description
This depletion-mode (normally-on) transistor utilizes an
advanced vertical DMOS structure and Supertex’s well-
proven silicon-gate manufacturing process. This combination
produces a device with the power handling capabilities of
bipolar transistors and with the high input impedance and
positive temperature coefficient inherent in MOS devices.
Characteristic of all MOS structures, this device is free
from thermal runaway and thermally-induced secondary
breakdown.
Supertex’s vertical DMOS FETs are ideally suited to a
wide range of switching and amplifying applications where
high breakdown voltage, high input impedance, low input
capacitance, and fast switching speeds are desired.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All
voltages are referenced to device ground.
