Features

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

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 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.
