and fast switching speeds
Excellent thermal stability
Integral Source-Drain diode
High input impedance and high gain
Complementary N- and P-channel devices
Advanced DMOS Technology
These enhancement-mode (normally-off) 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 inher-
ent 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 high breakdown
voltage, high input impedance, low input capacitance, and fast
switching speeds are desired.
Applications
Logic level interfaces – ideal for TTL and CMOS
Solid state relays
Battery operated systems
Photo voltaic drives
Analog switches
General purpose line drivers
Telecom switches
