P-Channel MOSFET, 250 mA, 90 V, 3-Pin TO-92 Microchip VP0109N3-G

The Microchip enhancement-mode (normally-off) transistor utilizes a vertical DMOS structure and Supertex’s 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. The 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.
