Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix 'Z' corresponds to the I-Pak tube packaging configuration. Confirm that the application environment meets the AEC-Q101 qualification requirements if automotive grade compliance is mandatory. Ensure thermal management designs account for the 1.05 K/W junction-to-case thermal resistance to maintain safe operating temperatures under load.

Single FETs, MOSFETs Selection Notes

Select this component when a logic-level N-channel MOSFET with high current handling is required in a TO-251AA footprint. The 11 mΩ typical on-resistance offers efficiency benefits over higher resistance alternatives. Consider the 42 A package-limited current rating against the 63 A silicon limit to determine appropriate heatsinking and PCB layout constraints for the target duty cycle.

Single FETs, MOSFETs Part Context

This part belongs to the Infineon HEXFET family, utilizing advanced trench process technology to minimize on-resistance per silicon area. The AUIRLU3110Z shares core electrical characteristics with the D-Pak variant AUIRLR3110Z but utilizes the I-Pak package form factor. It is designed specifically for demanding automotive environments requiring high reliability and thermal stability.

Single FETs, MOSFETs Replacement Considerations

AUIRLR3110Z serves as a functional equivalent with identical electrical specifications but utilizes a D-Pak (TO-252) package instead of I-Pak. Verify pinout compatibility and physical footprint differences before substitution.
