TN2124 N-Channel Enhancement-Mode Vertical DMOS FET Features General Description Free from secondary breakdown This low threshold, enhancement-mode (normally-off) Low power drive requirement transistor utilizes a vertical DMOS structure and Supertexs Ease of paralleling well-proven, silicon-gate manufacturing process. This Low C and fast switching speeds combination produces a device with the power handling ISS capabilities of bipolar transistors and the high input impedance Excellent thermal stability and positive temperature coefcient inherent in MOS devices. Integral source-drain diode Characteristic of all MOS structures, this device is free High input impedance and high gain from thermal runaway and thermally-induced secondary breakdown. Applications Supertexs vertical DMOS FETs are ideally suited to a wide Logic level interfaces ideal for TTL and CMOS range of switching and amplifying applications where very Solid state relays low threshold voltage, high breakdown voltage, high input Battery operated systems impedance, low input capacitance, and fast switching speeds Photo-voltaic drives are desired.
