Low Threshold N-Channel Enhancement-Mode

Vertical DMOS FET

General Description

The Supertex TN2425 is a low threshold enhancement-

mode (normally-off) transistor that 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.

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.
