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.
