General Description
The Supertex DN3145 is a depletion-mode (normally-on)
transistor utilizing 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
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.
