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 coefcient 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.

Drain-to-gate voltage BVDGS

Gate-to-source voltage ±20V

Operating and storage temperature -55°C to +150°C

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.
