P-Channel MOSFET, 125 mA, 400 V, 3-Pin TO-243AA Microchip TP2540N8-G

This low threshold, enhancement-mode (normally-off) transistor utilizes a vertical DMOS structure and well-proven, silicon-gate manufacturing process. This combination produces a device with the power handling capabilities of bipolar transistors and the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, this device is free from thermal runaway and thermally-induced secondary breakdown. Vertical DMOS FETs are ideally suited to a wide range of switching and amplifying applications where very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired.
