Fairchild FDP4020P FDB4020P Data Handbook
Summary
Fairchild FDP4020P/FDB4020P is a P-channel enhancement mode power MOSFET rated at -16A continuous drain current and -20V drain-source voltage, with low RDS(on) of 0.08 ohms at -4.5V gate drive. Designed for low voltage applications as a linear pass element or load switch, it features a high-density cell design for minimal on-resistance and is available in TO-220 and TO-263 packages. The device is rated for 175 degrees C maximum junction temperature with critical DC parameters specified at elevated temperatures. It targets power management applications including DC-DC converters requiring P-channel switching in through-hole and surface mount configurations.
