Low Threshold DMOS Technology
Low on resistance
These low threshold enhancement-mode (normally-off) transis-
tors utilize a 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
coefficient inherent in MOS devices. Characteristic of all MOS
structures, these devices are free from thermal runaway and
thermally-induced secondary breakdown.
Free from secondary breakdown
Low input and output leakage

Logic level interfaces – ideal for TTL and CMOS
Supertex’s vertical DMOS FETs are ideally suited to a wide range
of switching and amplifying applications where very low threshold
voltage, highbreakdownvoltage, highinputimpedance, lowinput
capacitance, and fast switching speeds are desired.
