Product details

60 V, 110 A N-channel — TO-220 through-hole power switch

It comes in a TO-220-3 through-hole package, which simplifies heatsink attachment and board-level rework compared to surface-mount alternatives.

Total gate charge Qg is 130 nC at Vgs = 10 V. The input capacitance Ciss is 4555 pF at Vds = 25 V, which influences the driver's peak current requirement during the Miller plateau. In practice, the junction-to-case thermal path through the TO-220 tab limits continuous power; derate linearly above 25 °C case temperature per the datasheet curve.

Frequently asked questions

What is the Rds(on) of IRFB7540PBF?

This is the on-resistance that determines conduction loss in high-current switching applications.

What is the gate charge of IRFB7540PBF?

This value is used to calculate the gate-drive power requirement and switching transition times.

Is IRFB7540PBF lead-free?

The part is ROHS3 compliant, meaning it meets the lead-free and restricted-substance requirements of the ROHS directive.
