Product details

P-channel 30 V, 5.8 A — SO-8 load switch

The Infineon IRF7406TRPBF is a HEXFET P-channel power MOSFET in a standard SO-8 surface-mount package. The 4.5 V drive voltage option (minimum Rds(on) at 10 V) means it can be driven from 5 V logic rails, though the 10 V drive delivers the lowest channel resistance. This is a straightforward load-switching or battery-protection MOSFET for designs that need a P-channel device in a compact SO-8 footprint.

Infineon no longer manufactures this part as a standard production item.

SO-8 footprint and thermal handling

The supplier device package is 8-SO. Power dissipation is rated at 2.5 W at 25°C ambient, which means the 8-SO copper footprint on the PCB must carry the heat — no exposed pad here.
