IRFZ44N N-Channel Power MOSFET – 55V, 49A – TO-220 Package

Datasheet

The IRFZ44N is a high-current N-channel power MOSFET designed for demanding switching and power control applications. Rated for 55V drain-source voltage and capable of handling up to 49A continuous drain current, it is well suited for automotive, industrial, and power electronics systems.

Manufactured using advanced HEXFET® technology, the IRFZ44N features very low RDS(on), enabling high efficiency with minimal conduction losses. Its fast switching characteristics and simple gate drive requirements make it ideal for DC-DC converters, motor drivers, inverters, and power supply circuits. The device is avalanche rated for improved ruggedness and supports easy paralleling for higher current applications.

Housed in a TO-220 through-hole package, the MOSFET provides excellent thermal performance and easy heat sinking, ensuring reliable operation under high load and elevated temperature conditions. With an operating junction temperature range up to 150°C, it delivers stable and long-term performance in harsh environments.
