General Description
This enhancement-mode (normally-off) transistor utilizes
a 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 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
very low threshold voltage, 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.
