General Description
The Supertex 2N6660 is an enhancement-mode (normally-
off) transistor that utilizes a vertical DMOS structure and
Supertex’s well-proven silicon-gate manufacturing process.
This combination produces a device with the power handling
capabilities of bipolar transistors, and the high input
impedance and positive temperature coefcient inherent
in MOS devices. Characteristic of all MOS structures, this
device is 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.
