Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The M3 suffix indicates halogen-free, RoHS compliant commercial grade, while HM3 denotes automotive grade. Ensure the package code matches the required delivery mode, such as 87A for 13-inch tape and reel quantities. Confirm terminal plating specifications against JESD standards for solderability.

Single Diodes Selection Notes

Select this component for applications requiring high efficiency and fast switching speeds. The TO-277A package offers a low profile suitable for automated placement. Consider thermal resistance values when designing heatsinking solutions. Verify that the 600 V rating meets the circuit's peak reverse voltage demands and that the 6.0 A current rating aligns with average load requirements.
