Supertex inc. DN3765 N-Channel Depletion-Mode Vertical DMOS FET Features General Description High input impedance This depletion-mode (normally-on) transistor utilizes an advanced vertical DMOS structure and Supertexs well- Low input capacitance proven silicon-gate manufacturing process. This combination Fast switching speeds produces a device with the power handling capabilities of Low on-resistance bipolar transistors and with the high input impedance and Free from secondary breakdown positive temperature coefficient inherent in MOS devices. Low input and output leakage Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary Applications breakdown. Normally-on switches Solid state relays Supertexs vertical DMOS FETs are ideally suited to a Converters wide range of switching and amplifying applications where Linear amplifiers high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired.
