The IRG4BC40WPBF is a Generation 4 UltraFast Insulated Gate Bipolar Transistor (IGBT) manufactured by Infineon Technologies. Designed for high-frequency switching applications, it features industry-benchmark switching losses and low conduction losses. The device utilizes an n-channel configuration with a collector-emitter voltage rating of 600V and a continuous collector current capacity of 40A. It is housed in a lead-free TO-220AB package suitable for through-hole mounting.
Verify the specific suffix WPBF indicates lead-free packaging and RoHS compliance when sourcing. Confirm the component status as discontinued or active through official Infineon channels prior to procurement. Ensure thermal management solutions align with the TO-220AB package specifications for reliable operation.
Select this component for applications requiring high efficiency at switching frequencies up to 150 kHz in hard-switched modes. It serves as a cost-effective alternative to power MOSFETs in higher power topologies. Consider its low minority-carrier recombination characteristics for resonant mode operations exceeding 300 kHz.
This discrete IGBT belongs to Infineon's UltraFast series, engineered specifically to address efficiency challenges in modern power conversion. The Generation 4 architecture represents an evolution in silicon technology, offering improved reliability and performance consistency over earlier iterations within the same voltage and current class.
