Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix 'TRL' corresponds to the Tape and Reel packaging format containing 800 units per reel. Confirm that the component meets the required AEC-Q101 qualification level for your specific automotive application environment. Ensure thermal management designs account for the specified junction-to-case thermal resistance values under actual operating conditions.

Single FETs, MOSFETs Selection Notes

Select this component when designing circuits requiring robust automotive-grade performance with high voltage tolerance up to 200V. The low on-resistance minimizes conduction losses in high-current applications. Consider the D2PAK package constraints for PCB footprint and thermal dissipation requirements compared to through-hole alternatives like TO-220 variants.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's HEXFET family of power MOSFETs, specifically designed for demanding automotive environments. It utilizes advanced silicon processing to achieve superior efficiency and thermal performance. The 'AU' prefix indicates its qualification for automotive applications, distinguishing it from standard industrial or consumer grade counterparts within the same electrical specification range.

Single FETs, MOSFETs Replacement Considerations

Direct pin-compatible replacements include IRFB4127 (TO-220 package) and IRFSL4127 (TO-262 package).
