Current and voltage limiters
General Description
These low threshold depletion-mode (normally-on) transistors
utilize an advanced 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.

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.
