Product details

It switches 48 A continuous drain current at 25°C case temperature with a maximum drain-source voltage of 60 V and a typical on-resistance of 23 mOhm at 10 V gate drive. The TO-220AB through-hole package suits it for power conversion, motor control, and DC-DC converter stages where board-level thermal management via a heatsink is standard.

This means Infineon has flagged it for eventual discontinuation; new designs should avoid it unless the BOM is locked and the production window is short. Buyers should evaluate a pin-compatible replacement for long-term supply resilience — a part with the same TO-220AB footprint, same 60 V / 48 A ratings is a common cross-shop candidate, though its lifecycle status should be verified independently.

Frequently asked questions

Is IRFZ44EPBF obsolete?

The IRFZ44EPBF is NRND (Not Recommended for New Designs), which means it is not yet discontinued but is on the path toward end-of-life. It is not recommended for new designs, but existing production can still source it through independent channels.

What is the replacement for IRFZ44EPBF?

A common pin-compatible alternative in the same TO-220AB footprint is the IRFZ44N, which shares the same 60 V Vdss and 48 A continuous drain ratings. Verify its lifecycle status independently before substituting into a new design.

IRFZ44EPBF vs IRFZ44N what is the difference?

Both are N-channel HEXFET MOSFETs in TO-220AB with 60 V Vdss and 48 A continuous drain. The IRFZ44EPBF is NRND; the IRFZ44N may still be active — check its current lifecycle status. The electrical ratings are functionally equivalent for most switching applications.
