General Description
This enhancement-mode (normally-off) transistor utilizes a
vertical DMOS structure and Supertex’s well-proven silicon-gate
manufacturing process. This combination produces a device 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,
this device is 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.
