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.","metaTitle":"IRFZ44EPBF HEXFET N-Channel MOSFET, 60V 48A TO-220AB","metaDescription":"IRFZ44EPBF N-Channel MOSFET, 60V Vdss, 48A continuous drain, 23mOhm Rds(on).
