Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix 'STRL' corresponds to the tape and reel packaging format containing 800 units per reel. Confirm that the component meets RoHS compliance requirements and holds the necessary automotive qualification certifications as specified by the manufacturer's documentation before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component when designing automotive circuits requiring robust performance under high thermal stress. The 175°C operating temperature rating provides significant headroom over standard industrial grades. Ensure the gate drive voltage aligns with the 10V specification to achieve the minimum on-resistance value listed in the datasheet specifications.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's HEXFET family of power MOSFETs, specifically tailored for automotive environments. The 'AU' prefix indicates automotive qualification status, while the 'S' denotes the surface-mount D2PAK package type. The 'TRL' suffix specifies the tape and reel delivery method, distinguishing it from tube-packaged variants within the same electrical family.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include the AUIRFB33N15D for through-hole TO-220AB applications or the IRF3315S for non-automotive grade surface mount needs. Verify pinout compatibility and thermal resistance characteristics when transitioning between different package types or qualification levels.
