Notes:

Absolute Maximum Ratings

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.

General Description

The Supertex DN3145 is a depletion-mode (normally-on)

transistor utilizing an advanced 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 coefﬁ 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

high breakdown voltage, high input impedance, low input

capacitance, and fast switching speeds are desired.
