General Description
Low threshold
High input impedance
Low input capacitance
Fast switching speeds
Low on-resistance
Free from secondary breakdown
Low input and output leakage
This low threshold, 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.
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
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.

Absolute Maximum Ratings are those values beyond which damage to the device may
occur. Functional operation under these conditions is not implied. Continuous operation
of the device at the absolute rating level may affect device reliability. All voltages are
