Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm packaging format. The standard tube pack contains 50 units, while the tape and reel variant (AUIRLS8409-7TRL) contains 800 units. Ensure compatibility with the required manufacturing process before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring robust automotive-grade performance and low thermal resistance. The D2PAK-7 pin package provides enhanced heat dissipation compared to standard configurations. Consider the 175°C operating limit and avalanche energy ratings when designing for high-stress transient conditions.

Single FETs, MOSFETs Part Context

This part belongs to the COOLiRFET family from Infineon Technologies, designed using advanced HEXFET processing techniques. It targets automotive environments where efficiency and durability are critical. The seven-terminal configuration facilitates superior thermal management and electrical performance relative to traditional three-terminal packages.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include the AUIRLS8409-7TRL for tape-and-reel requirements. Verify that any alternative maintains the same 40 V rating, 0.75 mΩ maximum RDS(on), and D2PAK-7 pin footprint to ensure mechanical and electrical compatibility.
