Free from secondary breakdown
Low input and output leakage
These low threshold depletion-mode (normally-on) transistors
utilize an advanced vertical DMOS structure and Supertex’s
well-proven silicon-gate manufacturing process. This combina-
tion produces devices with the power handling capabilities of
bipolar transistors and with the high input impedance and posi-
tivetemperaturecoefficientinherentinMOSdevices. Character-
istic of all MOS structures, these devices are free from thermal
runaway and thermally-induced secondary breakdown.
