Product details

The Infineon IRF7402TRPBF is a 20 V, 6.8 A N-channel MOSFET from the HEXFET series, built on a metal-oxide semiconductor process. Typical applications include low-voltage DC-DC converters, load switches, and battery management circuits where logic-level gate drive (2.7 V to 4.5 V) is available.

The maximum Rds(on) is 35 mΩ at 4.1 A drain current with a 4.5 V gate-source voltage. The drive voltage range for achieving the specified on-resistance is 2.7 V (minimum) to 4.5 V (maximum). That 35 mΩ figure is the worst-case ceiling at 4.5 V drive; at 2.7 V the resistance will be higher, so designs relying on the lower gate threshold should budget additional conduction loss.

The IRF7402TRPBF is marked obsolete per the manufacturer's product status. For BOM lines that still require this exact part, procurement must rely on independent distribution channels for remaining stock.

Frequently asked questions

What is the replacement for IRF7402TRPBF?

For a pin-compatible alternative, you would need to cross-reference the 8-SOIC footprint and 20 V / 6.8 A rating against current Infineon or equivalent N-channel MOSFETs. Our sourcing team can help identify a suitable substitute when you submit an RFQ.
