Additional Details

The FQB22P10 is a P-channel enhancement mode MOSFET. It has a drain-source voltage (Vds) rating of -100V and a continuous drain current (Id) rating of -22A. Its low on-resistance (Rds(on)) minimizes conduction losses. The device is available in a through-hole or surface-mount package. It requires a negative gate-source voltage (Vgs) to turn on. The gate threshold voltage (Vgs(th)) is the voltage required to start conduction. Proper gate drive is essential for optimal performance.
