Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base part number corresponds to the I-Pak tube configuration. Confirm that the procurement channel sources from authorized Infineon distributors to ensure authenticity and traceability. Check for any End-of-Life notices or alternative recommendations if long-term supply continuity is required for the production timeline.

Single FETs, MOSFETs Selection Notes

Select this component when designing for automotive environments requiring high voltage tolerance and thermal resilience. The 250V rating provides headroom for transient spikes common in automotive networks. Ensure gate drive voltages remain within the ±20V limit and verify that thermal management strategies keep the junction temperature below 175°C during peak load conditions.

Single FETs, MOSFETs Part Context

This device belongs to the International Rectifier (now Infineon) HEXFET family, specifically tailored for automotive grade requirements. The 'AU' prefix denotes automotive qualification, while 'I-Pak' identifies the TO-251AA surface-mount package. It serves as the lead-free, RoHS-compliant variant of the standard IRFR4292 series, offering enhanced reliability for critical vehicle electronics.

Single FETs, MOSFETs Replacement Considerations

The D-Pak variant AUIRFR4292 offers identical electrical specifications but utilizes a different footprint. Direct pin-to-pin replacement is not possible due to package differences; PCB redesign is required. No other direct substitutes are documented in the provided datasheet.
