TN2425 N-Channel Enhancement-Mode Vertical DMOS FET Features General Description Low threshold This low threshold, enhancement-mode (normally-off) High input impedance transistor utilizes a vertical DMOS structure and Supertexs Low input capacitance well-proven, silicon-gate manufacturing process. This Fast switching speeds combination produces a device with the power handling Low on-resistance capabilities of bipolar transistors and with the high input Free from secondary breakdown impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this Low input and output leakage device is free from thermal runaway and thermally-induced Applications secondary breakdown. Logic level interfaces ideal for TTL and CMOS Solid state relays Supertexs vertical DMOS FETs are ideally suited to a Battery operated systems wide range of switching and amplifying applications where Photo voltaic drives very low threshold voltage, high breakdown voltage, high Analog switches input impedance, low input capacitance, and fast switching General purpose line drivers speeds are desired.
