General Description

These depletion-mode (normally-on) transistors utilize an
advanced vertical DMOS structure and Supertex’s well-proven
silicon-gate manufacturing process. This combination produces
devices with the power handling capabilities of bipolar transistors
and with the high input impedance and positive temperature

coefcient inherent in MOS devices. Characteristic of all MOS

structures, these devices are 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.
