IRF6646TRPBF Description

Short technical summary and product information.

The IRF6646TRPBF is an N-Channel Power MOSFET from Infineon Technologies, designed for high-performance power conversion applications. It features a maximum drain-source voltage of 80V and a continuous drain current of 12A at 25°C ambient temperature (68A at case temperature 25°C). The device offers a low maximum on-resistance of 9.5mOhm at 12A and 10V gate drive, with a typical value of 7.6mOhm. The total gate charge is typically 36nC, enabling efficient switching.

 

This MOSFET is optimized for primary side bridge topologies in isolated DC-DC converters, particularly for 48V input voltage range systems (36V to 60V ETSI). It is also suitable for synchronous rectification and other high-efficiency power supply designs. The DirectFET Isometric MN package provides a low profile (under 0.7mm) and supports dual-sided cooling for improved thermal performance. It is surface mount compatible and RoHS compliant with lead-free qualification up to 260°C reflow.

 

The device includes avalanche energy capability of 230mJ (single pulse) and is designed for high Cdv/dt immunity. Operating junction temperature range is -40°C to 150°C.
