Diode Arrays Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to confirm package type and packing quantity. Confirm compliance requirements such as RoHS and halogen-free status directly from the datasheet. Ensure that any suffixes or variants match the exact electrical specifications required for the target application before finalizing procurement.

Diode Arrays Selection Notes

Select this component based on its 200 V reverse voltage rating and 10 A continuous current capacity. Consider the 50 ns reverse recovery time for switching frequency requirements. Evaluate thermal management needs given the 1.5 °C/W junction-to-case thermal resistance. Verify if AEC-Q101 automotive qualification is necessary, which requires selecting the 'H' suffix variant.

Diode Arrays Part Context

This part belongs to the HER1001G–HER1008G series of glass passivated high-efficient rectifiers. The series covers voltage ratings from 50 V to 1000 V while maintaining a consistent 10 A forward current rating across all models. The HER1003G specifically addresses the 200 V requirement within this standardized product family.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include HER1001G (50V), HER1002G (100V), HER1004G (300V), HER1005G (400V), HER1006G (600V), HER1007G (800V), and HER1008G (1000V). Ensure the replacement matches the 200 V reverse voltage specification exactly.
