N-Channel Enhancement-Mode
Vertical DMOS FET
Features
General Description
► Low threshold (2.0V max.)
This low threshold, enhancement-mode (normally-off)
transistor utilizes a 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.
► High input impedance
► Low input capacitance (125pF max.)
► Fast switching speeds
► Low on-resistance
► Free from secondary breakdown
► Low input and output leakage
Applications
► Logic level interfaces - ideal for TTL and CMOS
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.
► Solid state relays
► Battery operated systems
► Photo voltaic drives
► Analog and Telecom switches
► General purpose line drivers
