N-Channel Enhancement-Mode
Vertical DMOS FETs
Features
General Description
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.
► Low threshold (2.0V max.)
► High input impedance
► Low input capacitance
► Fast switching speeds
► Low on-resistance
► Free from secondary breakdown
► Low input and output leakage
Applications
► Logic level interfaces - ideal for TTL and CMOS
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.
► Solid state relays
► Battery operated systems
► Photo voltaic drives
► Analog switches
► General purpose line drivers
► Telecom switches

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 referenced to device ground.
