Features
Low Threshold DMOS Technology
❏ Low threshold
These low threshold enhancement-mode (normally-off) transistors 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.
❏ High input impedance
❏ Low input capacitance
❏ Fast switching speeds
❏ Low on resistance
❏ Free from secondary breakdown
❏ Low input and output leakage
Supertex 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.
❏ Complementary N- and P-channel devices
Applications
❏ Logic level interfaces – ideal for TTL and CMOS
❏ Solid state relays
Package Option
❏ Photo voltaic drives
❏ Analog switches
❏ General purpose line drivers
❏ Telecom switches
