Single FETs, MOSFETs Procurement Notes

Verify the complete part number including the suffix '-7TRL' to ensure correct packaging and automotive grade specification. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for obsolescence notices or lifecycle status updates directly from Infineon. Ensure sourcing from authorized distributors to guarantee authenticity and traceability for automotive supply chain requirements.

Single FETs, MOSFETs Selection Notes

Select this component when high current capacity and low conduction losses are critical in automotive power stages. The 150 V rating suits 12V and 24V automotive systems with transient protection needs. Consider the D2PAK-7 package for its superior thermal dissipation compared to standard TO-263 variants. Evaluate gate charge requirements against driver capabilities to optimize switching speed and minimize switching losses.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's StrongIRFET family, designed specifically for automotive applications requiring high efficiency and reliability. It represents an evolution of the IRFS4115 series with added automotive qualification. The 'A' prefix denotes automotive grade, while '-7' indicates the 7-pin D2PAK package variant. This distinguishes it from standard industrial grades and other package options within the same electrical family.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes may include IRFS4115-7P for non-automotive applications, though automotive qualification must be verified. Cross-reference with other StrongIRFET devices offering similar Rds(on) and Vds ratings. Ensure pinout compatibility and thermal characteristics match the existing design constraints before substitution.
