N-Channel Enhancement-Mode
Vertical DMOS FETs
Features
General Description
►
Free from secondary breakdown
►
Low input and output leakage
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.
►
Low C
ISS
and fast switching speeds
►
High input impedance and high gain
Applications
►
Motor controls
►
Converters
Supertex’s vertical DMOS FE
T
s
a
re 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.
►
Amplifiers
►
Switches
►
Power supply circuits
►
Drivers (relays, hammers, solenoids, lamps,
memories, displays, bipolar transistors, etc.)
