DN2540 Supertex inc. N-Channel Depletion-Mode Vertical DMOS FETs Features General Description High input impedance The Supertex DN2540 is a low threshold depletion mode (normally-on) transistor utilizing an advanced vertical Low input capacitance DMOS structure and Supertexs well-proven silicon-gate Fast switching speeds manufacturing process. This combination produces a device Low on-resistance with the power handling capabilities of bipolar transistors Free from secondary breakdown and with the high input impedance and positive temperature Low input and output leakage coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and Applications thermally-induced secondary breakdown. Normally-on switches Supertexs vertical DMOS FETs are ideally suited to a Solid state relays wide range of switching and amplifying applications where Converters high breakdown voltage, high input impedance, low input Linear amplifiers capacitance, and fast switching speeds are desired.
