IRFZ44EPBF

IRFZ44EPBF Description

The IRFZ44EPBF from Infineon Technologies is an N-channel HEXFET® power MOSFET designed for high-efficiency switching applications. With a 60V drain-to-source voltage (Vdss) and 48A continuous drain current (Id), it delivers robust performance in power management circuits. This device features a low on-resistance (Rds(on)) of 23mΩ at 10V gate drive, minimizing conduction losses and improving thermal efficiency. Though marked as "Not For New Designs", it remains a reliable choice for legacy systems requiring high-current handling and fast switching capabilities. Packaged in a TO-220AB through-hole format, it is suitable for industrial and automotive environments where durability is critical.

IRFZ44EPBF Features

• Low Rds(on): 23mΩ at 29A, 10V ensures reduced power dissipation.
• High Current Capacity: Supports up to 48A (Tc) for demanding loads.
• Fast Switching: Gate charge (Qg) of 60nC at 10V enables efficient high-frequency operation.
• Wide Voltage Range: ±20V gate-to-source voltage (Vgs) tolerance.
• Thermal Efficiency: 110W max power dissipation (Tc) with robust thermal performance.
• Compliance: ROHS3 and REACH compliant, meeting environmental standards.
