2N6660/2N6661
N-Channel Enhancement-Mode
Vertical DMOS FETs
Features
General Description
► 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
► Complementary N- and P-Channel devices
The Supertex 2N6660 and 2N6661 are enhancement-
mode (normally-off) transistors that utilizes a vertical
DMOS structure and Supertex’s well-proven silicon-gate
manufacturingprocess.Thiscombinationproducesdevices
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, these devices are free from thermal
runaway and thermally-induced secondary breakdown.
Applications
► Motor controls
► Converters
► Amplifiers
► 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.
► Power supply circuits
► Drivers (relays, hammers, solenoids, lamps,
memories, displays, bipolar transistors, etc.)

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.
