Product details

9.1 mOhm Rds(on) — the conduction-loss ceiling

The IRF7821TRPBF: The 9.1 mOhm maximum on-resistance at Vgs=10 V and 13 A sets the conduction loss floor for a 30 V switch in this footprint.

Gate drive and switching profile

Gate charge is 14 nC at 4.5 V, and the drive voltage range spans 4.5 V to 10 V. Input capacitance is 1010 pF at 15 V Vds.

Temperature range and board-level fit

Junction temperature range is -55°C to 155°C, covering industrial and automotive under-hood environments. Power dissipation is rated at 2.5 W at 25°C ambient — real-world derating to 1.5 W at 85°C is typical for a 1 oz copper board.

Sourcing and compliance

ROHS3 compliant.

Frequently asked questions
