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.

Note 1. Distance of 1.6mm from case for 10 seconds.

General Description

The Supertex DN1509 is suitable for high voltage transient

protection for LDO in automobile applications during “load

dump” conditions.

This

transistor utilizes 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

very low threshold voltage, high breakdown voltage, high

input impedance, low input capacitance, and fast switching

speeds are desired.
