N-Channel Enhancement-Mode  

Vertical DMOS FET  

Features  

General Description  

►

Free from secondary breakdown  

►

Low power drive requirement  

►

Ease of paralleling  

This 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.  

►

Low C

ISS

and fast switching speeds  

►

Excellent thermal stability  

►

Integral source-drain diode  

►

High input impedance and high gain  

Applications  

►

Motor controls  

►

Converters

a

re 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.
