IRFB7440PBF Description

Short technical summary and product information.

The Infineon IRFB7440PBF is an N-channel power MOSFET designed for various applications including motor drives, battery-powered circuits, and DC/DC converters. It offers a drain-source voltage (VDS) of 40V and a low typical on-resistance (RDS(on)) of 2mΩ when measured at a gate-source voltage (VGS) of 10V and a drain current (ID) of 100A. The maximum continuous drain current is rated at 172A at 25°C case temperature, with a package-limited continuous drain current of 120A.

This MOSFET is built with HEXFET technology, providing improved gate, avalanche, and dynamic dv/dt ruggedness. It is fully characterized for capacitance and avalanche SOA, and features enhanced body diode dV/dt and dI/dt capability. The component is RoHS compliant and halogen-free.

The IRFB7440PBF is packaged in a TO-220AB case, suitable for through-hole mounting. The standard package quantity is 50 units per tube.
