Low Threshold DMOS Technology
These low threshold enhancement-mode (normally-off) transis-
tors 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.
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.
Applications
■ Logic level interfaces – ideal for TTL and CMOS
■ Solid state relays
■ Battery operated systems
■ Photo voltaic drives
■ Analog switches
■ General purpose line drivers
■ Telecom switches
