N-Channel Enhancement-Mode
Vertical DMOS FET
General Description
Features
►
►
►
►
►
►
►
Free from secondary breakdown
Low power drive requirement
Ease of paralleling
Low CISS and fast switching speeds
Excellent thermal stability
Integral source-drain diode
High input impedance and high gain
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.

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.

Operating and storage temperature
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.
