IRFH7440TRPBF Description

Short technical summary and product information.

The IRFH7440TRPBF is a N-Channel power MOSFET from Infineon Technologies' StrongIRFET family, utilizing HEXFET technology. It is designed for high-current switching applications with a drain-source voltage rating of 40V and continuous drain current of 159A at 25°C case temperature (101A at 100°C). The device features a typical on-resistance of 1.8mOhm and maximum of 2.4mOhm at 10V gate drive, with a gate threshold voltage range of 2.2V to 3.9V.

 

This MOSFET offers a pulsed drain current capability of 636A and single pulse avalanche energy of 232mJ. It is optimized for brushed and brushless DC motor drives, PWM inverter topologies, battery-powered circuits, half-bridge and full-bridge configurations, synchronous rectification, and resonant mode power supplies. The device is RoHS compliant and free of lead and halogen.

 

Packaged in an 8-PowerTDFN (PQFN 5x6) surface mount package, it has a maximum power dissipation of 104W at 25°C case temperature and a junction-to-case thermal resistance of 1.2°C/W. The operating junction temperature range is -55°C to 150°C.
