Procurement Notes

Verify the specific ordering suffix 'X' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the component matches the LFPAK56D (SOT1205) package outline and marking code '91760E'. Confirm compliance with RoHS directives and REACH regulations prior to integration. Cross-reference the datasheet revision date to ensure the latest electrical characteristics are applied during design validation.

Selection Notes

Select this component when a dual N-channel solution is required for 60 V automotive circuits. The low on-state resistance supports efficient power switching in motor and solenoid drivers. Verify that the thermal management strategy accommodates the 53 W power dissipation limit at the intended mounting base temperature. Ensure the gate drive voltage meets the logic level requirements for full enhancement at operating temperatures up to 175 °C.
