General Description
The Supertex TN2540 is a low threshold enhancement-
mode transistor that utilizes 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 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.
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.
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
Battery operated systems
Photo voltaic devices
