N-Channel Enhancement-Mode
Vertical DMOS FET
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 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 very
low threshold voltage, high breakdown voltage, high input
impedance, low input capacitance, and fast switching speeds
are desired.
Low threshold (2.0V max.)
High input impedance
Low input capacitance (125pF max.)
Fast switching speeds
Low on-resistance
Free from secondary breakdown
Low input and output leakage

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
