Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging configuration and reel specifications. Confirm compliance requirements such as RoHS and REACH status directly with the supplier or datasheet before procurement. Ensure the component version matches the required production data sheet status for your design timeline.
Selection Notes
Select this component for designs requiring automotive qualification and operation up to 175 °C junction temperature. Evaluate PCB thermal design carefully, as practical current limits are often determined by board layout rather than the absolute maximum rating. Consider the repetitive avalanche capability if the application involves inductive load switching.
Part Context
This part belongs to Nexperia's standard level MOSFET portfolio designed for automotive environments. It employs SOT1210 surface-mount packaging, which utilizes gull wing leads to facilitate high manufacturability and automated optical inspection during assembly processes.
Replacement Considerations
Consult the official Nexperia replacement guide for verified substitutes. Cross-reference key parameters including RDS(on), package dimensions, and thermal characteristics to ensure compatibility.
