Absolute Maximum Ratings
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.
*Distance of 1.6mm from case for 10 seconds.
-G indicates package is RoHS compliant (‘Green’)

General Description
These 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 coeffi cient 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
high breakdown voltage, high input impedance, low input
capacitance, and fast switching speeds are desired.
