Single FETs, MOSFETs Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Infineon Technologies. Procurement requires verification of existing stock availability through authorized distributors or third-party suppliers. Buyers must confirm RoHS compliance status, as some sources indicate non-compliance due to lead content. Replacement planning should prioritize active equivalents to ensure long-term supply chain stability.

Single FETs, MOSFETs Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. The 30V rating and 8.5A current limit define its operational envelope. Designers should verify that the 22mOhm on-resistance meets system efficiency requirements. Alternative components with similar electrical characteristics but active manufacturing status are recommended for new implementations to avoid future sourcing risks.

Single FETs, MOSFETs Part Context

The IRF7403TR belongs to the HEXFET family of power MOSFETs, representing International Rectifier's legacy silicon technology now under Infineon ownership. It was designed for general-purpose power switching applications requiring moderate voltage and current handling. The 8-SOIC package provides a compact solution for space-constrained designs, though its discontinuation reflects industry shifts toward higher density and more efficient packaging technologies.
