Product details

100 V, 130 A — where the rating limits bite

In a real enclosure at 85°C ambient, derate per the power dissipation ceiling of 300 W at the case; the junction temperature limit of 175°C is the hard stop.

Gate charge and drive budget

Total gate charge is 250 nC at 10 V.

Through-hole package and thermal path

The TO-220-3 (TO-220AB) package is a through-hole mount with a metal tab for heatsink attachment. The 300 W power dissipation rating assumes the tab is bolted to an infinite heatsink — real-world dissipation is limited by the thermal interface and airflow. The -55°C to 175°C junction range covers military-temperature applications; the 4 V threshold at 250 µA is a standard logic-level turn-on, but the drive voltage for minimum Rds(on) is 10 V.

Frequently asked questions

What is the Rds(on) of IRFB4310PBF?

The maximum Rds(on) is 7 mOhm at 75 A drain current with 10 V gate-to-source drive. This is the on-resistance at the rated drive voltage; actual resistance rises with junction temperature per the normalised curve in the datasheet.

Is IRFB4310PBF RoHS compliant?

Yes, it is ROHS3 compliant. The Pb-free suffix in the order code confirms lead-free construction.

What is the maximum drain current of IRFB4310PBF?

The continuous drain current rating is 130 A at 25°C case temperature. Derate for higher case temperatures per the power dissipation limit of 300 W.
