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