Product details

2.95 mOhm Rds(on) — the conduction loss floor

The IRFH8316TRPBF-IR is an Infineon HEXFET® N-channel power MOSFET rated for 30 V drain-source and 27 A switching current. For a 12 V bus load switch or a low-side synchronous rectifier, that on-resistance keeps the heatsink small or absent.

59 nC gate charge — what the driver sees

Gate charge totals 59 nC at 10 V Vgs. The ±20 V Vgs rating gives headroom for gate-drive overshoot on a 12 V rail without avalanche stress on the oxide.

Junction temperature range and package

The 2.2 V maximum gate threshold at 50 µA drain current means the part turns on fully with 5 V logic, though the lowest Rds(on) requires the full 10 V drive.

Frequently asked questions

What is the exact Rds(on) of IRFH8316TRPBF-IR?

The maximum Rds(on) is 2.95 mOhm at 20 A drain current with a 10 V gate-source voltage. This is the worst-case value at 25 °C junction temperature; actual on-resistance rises with temperature per the normalised curve in the datasheet.

Does IRFH8316TRPBF-IR have a Pb-free finish?

The part number suffix 'TRPBF' indicates a Pb-free (RoHS-compliant) plating finish. The 'IR' suffix denotes Infineon's standard reel packaging.
