Single Diodes Procurement Notes

Verify the specific suffix 'H' indicates AEC-Q101 automotive qualification status as defined by the manufacturer's ordering code structure. Confirm the package type is ITO-220AC and check for RoHS compliance documentation. Ensure the part number matches the exact voltage rating required for the circuit design before procurement.

Single Diodes Selection Notes

Select this component when a 200V reverse voltage rating and 10A continuous forward current are required. Consider the ITO-220AC package size for thermal management needs. Evaluate the low forward voltage characteristics for efficiency optimization in switching applications. Verify that the operating temperature range aligns with the system environment.

Single Diodes Part Context

This device belongs to the HERAF1001G through HERAF1008G series, which share identical electrical specifications except for the repetitive peak reverse voltage ratings ranging from 50V to 1000V. All variants maintain the same 10A forward current capacity and utilize the same ITO-220AC package configuration for consistent mechanical integration across different voltage requirements.

Single Diodes Replacement Considerations

Direct substitutes must match the 200V VRRM, 10A IF rating, and ITO-220AC package. Verify equivalent thermal resistance and reverse recovery time specifications. Ensure the replacement component also offers glass passivation if environmental robustness is critical.
