Advanced DMOS Technology
Not recommended for new designs. For products in TO-92
(N3) package and TO-243AA (N8) package, please use DN3535
or DN3545 instead.
These low threshold depletion-mode (normally-on) transistors
utilize an advanced vertical DMOS structure and Supertex’s
well-proven silicon-gate manufacturing process. This combina-
tion produces devices with the power handling capabilities of
bipolar transistors and with the high input impedance and posi-
tive temperature coefficient inherent in MOS devices. Character-
istic 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 high breakdown
voltage, high input impedance, low input capacitance, and fast
switching speeds are desired.
