Single FETs, MOSFETs Procurement Notes

Verify the manufacturer designation as Infineon Technologies, noting that International Rectifier was acquired. Confirm the specific suffix 'ZS' corresponds to the DPAK (TO-252) package variant. Ensure compliance requirements match the intended deployment region, as older HEXFET variants may not meet current RoHS standards without specific verification.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring high current handling up to 89 A with low voltage drop. The DPAK package suits surface-mount designs with moderate thermal constraints. Compare gate charge specifications against driver capabilities to ensure adequate switching speed. Verify thermal resistance values if operating near the maximum junction temperature limit.

Single FETs, MOSFETs Part Context

This part belongs to the HEXFET family of power MOSFETs, known for high efficiency and ruggedness. The AUIRL3705ZS represents a specific configuration within the IRL3705 product line, tailored for automotive or industrial environments given the 'AU' prefix often denoting automotive qualification. It serves as a discrete power switch solution replacing older bipolar transistor technologies.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include the IRL3705ZL in TO-262 packaging for through-hole applications, though pin compatibility differs. The AUIRFR3710ZTRR offers similar functionality but with higher voltage ratings. Verify pinout and thermal pad configurations before swapping packages.
