International Rectifier Component Intelligence

The IR catalog is most commonly associated with power MOSFETs, rectifier diodes, and PMIC regulator or controller products, including devices for power conversion and DDR power applications.

PartGenie provides a searchable manufacturer catalog when source catalog data is available; this hub is the intelligence and navigation layer for IR product families, lifecycle checks, sourcing risks, and comparison paths.

Only after engineering review. Match package, pinout, voltage, current, RDS(on), gate charge, thermal performance, avalanche or recovery behavior where relevant, and qualification requirements before approving a pin-compatible or functional alternative.

Because International Rectifier is now part of Infineon, catalog systems may show legacy IR names, Infineon references, or distributor-specific alternate codes. Use the current orderable part number and datasheet as the control point.
