The IRFB7446PBF is an N-Channel power MOSFET from Infineon Technologies, part of the StrongIRFET family. It features a drain-source voltage rating of 40V and a continuous drain current of 120A (package limited) or 123A (silicon limited) at 25°C. The device offers a typical on-resistance of 2.6mOhm and a maximum of 3.3mOhm at Vgs=10V, Id=70A. This low on-resistance minimizes conduction losses in high-current applications.
The MOSFET is designed for motor drive applications, battery powered circuits, half-bridge and full-bridge topologies, synchronous rectification, and DC/DC converters. It is housed in a through-hole TO-220AB package (TO-220-3) and is supplied in tube packaging with a standard quantity of 50. The device is lead-free, RoHS compliant, and halogen-free.
It has an operating junction temperature range of -55°C to 175°C and a maximum power dissipation of 99W at 25°C case temperature. The gate threshold voltage ranges from 2.2V to 3.9V, and the maximum gate-source voltage is ±20V. Input capacitance is 3183pF at Vds=25V, and total gate charge is 93nC at Vgs=10V. The device also features a single pulse avalanche energy rating of 236mJ (L=1mH).
