What this MOSFET is and where it fits
The Infineon IRF6722MTRPBF is an N-channel enhancement-mode power MOSFET from the HEXFET family, built for low-voltage (<30 V) switching and load-management roles. It carries a continuous drain current of 13 A and a pulsed rating of 56 A, with a maximum on-resistance of 7.7 mOhm at a 10 V gate drive. The DIRECTFET package keeps the footprint small and the thermal path short — useful for dense power stages, point-of-load converters, and battery-protection circuits where board space is tight and junction temperatures can hit 150°C.
Key ratings and what they mean for the BOM
The 7.7 mOhm Rds(on) at 10 V gate drive drives conduction loss. At 13 A, dissipation is within the 2.3 W package limit. The 17 nC gate charge at 4.5 V allows fast switching.
