General Description
High input impedance
Low input capacitance
Fast switching speeds
Low on-resistance
Free from secondary breakdown
Low input and output leakage
The Supertex DN3145 is a 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.

Part Number
DN3145N8-G
Package Option
TO-243AA (SOT-89)
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.
