P-Channel load switch in an SOIC-8
The Infineon IRF7406PBF is a P-Channel enhancement-mode MOSFET from the HEXFET® series, housed in an SOIC-8 surface-mount package. It is designed for high-side load switching and battery protection in 12 V and 24 V systems where a P-Channel simplifies the gate drive — no charge pump needed.
45 mΩ on-resistance — what it means at the bench
At 4.5 V gate drive the resistance roughly doubles — check the typical curve in the datasheet if your gate drive is logic-level. For a 2 A load at 10 V gate drive, conduction loss runs about 180 mW, well within the 2.5 W package dissipation at 25°C ambient.
Temperature range and rework notes
The SOIC-8 package is rework-friendly — a hot-air station at 300°C for 30 seconds lifts the part cleanly without pad damage.
