General Description
The Supertex DN3525 is a low threshold 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
coefficient inherent in MOS devices. Characteristic of all
MOS structures, this device is free from thermal runaway and
thermally-induced secondary breakdown.
High input impedance
Low input capacitance
Fast switching speeds
Low on resistance
Free from secondary breakdown
Low input and output leakage

►
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.
Normally-on switches

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.
