IRFZ44NPBF Description

Short technical summary and product information.

The Infineon IRFZ44NPBF is an advanced HEXFET Power MOSFET utilizing high-performance processing techniques to achieve low on-resistance per silicon area. This device offers fast switching speeds and a ruggedized design, making it suitable for a wide array of applications.

Key electrical specifications include a drain-to-source breakdown voltage (Vds) of 55V and a continuous drain current (Id) of 49A at 25°C case temperature. The gate-to-source voltage (Vgs) is rated up to ±20V. Thermal characteristics include a junction-to-case thermal resistance (Rthjc) of 1.5°C/W and a junction-to-ambient thermal resistance (Rthja) of 62°C/W.

Packaged in the industry-standard TO-220AB, this MOSFET is well-suited for commercial-industrial applications with power dissipation up to 94W. The TO-220 package's low thermal resistance and cost contribute to its widespread acceptance.

This MOSFET operates within a junction temperature range of -55°C to +175°C and is RoHS3 compliant and lead-free.
