General Description
This low threshold enhancement-mode (normally-off) tran-
sistor 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 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 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.
