General Description
The Supertex TC7920 consists of two pairs of high voltage, low
threshold N-channel and P-channel MOSFETs in a 12-Lead
DFN package. All MOSFETs have integrated the output drain
high voltage diodes, 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, 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 very low threshold
voltage, high breakdown voltage, high input impedance, low input
and output capacitance, and fast switching speeds are desired.
