General Description
The Supertex TC8020 consists of six pairs of high voltage,
low threshold N- and P-channel MOSFETs in a 56-lead QFN
package. All MOSFETs have integrated gate-to-source resistors
and gate-to-source Zener diode clamps which are desired for
high voltage pulser applications. The complimentary, high-speed,
high voltage, gate-clamped N- and P-channel MOSFET pairs
utilize an advanced 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 with the high input impedance and positive
temperature coefficient 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 and output capacitance, and fast switching
speeds are desired.
