General Description
The Supertex DN1509 is suitable for high voltage transient
protection for LDO in automobile applications during 鈥渓oad
dump鈥?conditions.
This low threshold, depletion-mode (normally-on)
transistor utilizes an advanced vertical DMOS structure
and Supertex鈥檚 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鏗乧ient inherent in MOS devices. Characteristic of all
MOS structures, this device is free from thermal runaway
and thermally-induced secondary breakdown.
Supertex鈥檚 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.
