TN2425
Low Threshold N-Channel Enhancement-Mode
Vertical DMOS FET
Features
General Description
► Low threshold
► High input impedance
► Low input capacitance
► Fast switching speeds
The Supertex TN2425 is a low threshold enhancement-
mode (normally-off) transistor that utilizes a vertical
DMOS structure and Supertex’s well-proven silicon-gate
manufacturingprocess.Thiscombinationproducesadevice
with the power handling capabilities of bipolar transistors,
and 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.
► Low ON-resistance
► Free from secondary breakdown
► Low input and output leakage
► Complementary N- and P-Channel devices
Applications
► Logic level interfaces – ideal for TTL and CMOS
► Solid state relays
► Medical ultrasound pulsers
► Analog switches
Supertex’s 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.
► General purpose line drivers
► Telecom 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.
