TP2635/TP2640
P- Channel Enhancement-Mode
Vertical DMOS FETs
Features
General Description
► Low threshold — -2.0V max.
► High input impedance
► Low input capacitance
► Fast switching speeds
► Low on resistance
► Free from secondary breakdown
► Low input and output leakage
► Complementary N- and P-channel devices
These low threshold enhancement-mode (normally-off)
transistors utilize a vertical DMOS structure and Supertex’s
well-proven 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.
Applications
► Logic level interfaces – ideal for TTL and CMOS
► Solid state relays
► Battery operated systems
► Photo voltaic drives
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.
► Analog switches
► 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.
