Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix required for your production needs. The standard tube packaging corresponds to part number AUIRFR3710Z, while tape and reel options are available under AUIRFR3710ZTRL. Confirm that the component meets the necessary automotive qualification standards for your intended application environment before finalizing procurement.

Single FETs, MOSFETs Selection Notes

Select this component when automotive reliability and high thermal performance are required. The 175°C junction temperature rating allows for operation in demanding environments. Ensure the design accounts for the package-limited current of 42A if thermal constraints prevent reaching the silicon-limited 56A rating. Verify gate drive requirements against the specified threshold voltage range.
