Single FETs, MOSFETs Procurement Notes

Verify the specific revision level against the manufacturer's official datasheet before finalizing designs. Confirm that the TO-247AC package dimensions match the target PCB footprint requirements. Ensure the design accounts for the package-limited current rating of 195A under appropriate thermal conditions rather than the silicon-limited value.

Single FETs, MOSFETs Selection Notes

Select this component when a 40V rating is sufficient and low conduction losses are critical. The TO-247AC package provides robust mechanical mounting and thermal dissipation capabilities suitable for through-hole implementations. Consider the 1.70mΩ maximum RDS(on) for efficiency calculations at full load currents up to the package limit.

Single FETs, MOSFETs Part Context

This part belongs to the Infineon (formerly International Rectifier) HEXFET family of power MOSFETs. The 'AU' prefix indicates compliance with automotive industry requirements regarding product discontinuance and process change notifications. It utilizes silicon-based technology optimized for high reliability in demanding environments.

Single FETs, MOSFETs Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may not meet the specific AEC-Q101 qualification or the exact pinout and thermal characteristics required for direct substitution without circuit re-evaluation.
