Description
This low threshold, depletion-mode, normally-on, tran-
sistor utilizes an advanced vertical Diffusion Metal
Oxide Semiconductor (DMOS) structure and a well
proven silicon-gate manufacturing process. This com-
bination produces a device with the power-handling
capabilities of bipolar transistors, plus the high-input
impedance and positive-temperature coefficient inher-
ent in Metal-Oxide Semiconductor (MOS) devices.
Characteristic of all MOS structures, this device is free
from thermal runaway and thermally-induced second-
ary breakdown.
Vertical DMOS Field-Effect Transistors (FETs) are ide-
ally suited to a wide range of switching and amplifying
applications where a very low threshold voltage, high
breakdown voltage, high input impedance, low input
capacitance, and fast switching speeds are desired.
