Low Threshold DMOS Technology
These low threshold enhancement-mode (normally-off) power
transistors 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.
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.
