Single FETs, MOSFETs Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and tape/reel specifications. Confirm that the component grade matches industrial requirements. Check for any RoHS compliance documentation relevant to your region. Ensure the manufacturer part number matches exactly to avoid counterfeit risks.

Single FETs, MOSFETs Selection Notes

Select this component when a 650 V rating and 12.5 A current capacity are required in a small form factor. The low Rds(on) makes it suitable for applications prioritizing conduction losses. Compare thermal resistance values against your PCB copper area capabilities. Consider the gate charge characteristics if driving speed is critical for the target switching frequency.

Single FETs, MOSFETs Part Context

This part belongs to the MDmesh M5 family, which combines vertical process technology with horizontal layout structures. This design achieves industry-leading Rds(on) per unit area. The PowerFLAT package offers improved thermal performance compared to traditional leaded packages while maintaining a low profile for space-constrained electronics.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes within the same series include STL31N65M5 and STL18N65M5, though these differ in current ratings and package pin counts. Verify compatibility before swapping, as package dimensions and thermal characteristics vary significantly between PowerFLAT variants and TO-263 packages.
