Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm packaging format, such as tube or tape and reel quantities. Ensure the component meets the required industrial qualification level per JEDEC JESD47F. Confirm moisture sensitivity level MSL1 compliance for surface mount assembly processes. Cross-reference the part marking to validate lead-free status and assembly site codes prior to integration into production lines.

Single FETs, MOSFETs Selection Notes

Select this component for designs requiring low on-resistance and high current handling in compact D-Pak packages. Evaluate thermal management requirements based on the 1.05°C/W junction-to-case resistance. Consider the 75V voltage rating and 87A current capacity for appropriate headroom in power stages. Review the avalanche energy ratings if unclamped inductive switching is present in the circuit topology.

Single FETs, MOSFETs Part Context

This part belongs to the StrongIRFET family from Infineon Technologies, formerly International Rectifier. It utilizes HEXFET technology optimized for efficiency and ruggedness. The IRFR7740PbF variant specifically denotes the D-Pak package form factor, distinguishing it from the I-Pak IRFU7740PbF counterpart within the same electrical specification set.

Single FETs, MOSFETs Replacement Considerations

The IRFU7740PbF serves as a pin-compatible alternative in the I-Pak (TO-251AA) package with identical electrical characteristics. Verify footprint compatibility when substituting between D-Pak and I-Pak variants. No other direct substitutes are documented in the provided datasheet.
