Description
2N6661 is an enhancement-mode (normally-off) tran-
sistor that utilizes a vertical DMOS structure and a well-
proven silicon-gate manufacturing process. This com-
bination produces a device with the power-handling
capabilities of bipolar transistors, and the high input
impedance and positive temperature coefficient inher-
ent in MOS devices. Characteristic of all MOS struc-
tures, this device is free from thermal runaway and
thermally-induced secondary breakdown.
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.
