DN3545
N-Channel Depletion-Mode
Vertical DMOS FET
Features
General Description
►
►
►
►
►
►
These depletion-mode (normally-on) transistors utilize an
advanced vertical DMOS structure and Supertex’s wellproven silicon-gate manufacturing process. This combination
produces devices 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, these devices are 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
Applications
►
►
►
►
►
►
►
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.

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.
