Diode Arrays Procurement Notes

Verify the specific ordering code matches the required voltage rating and packaging format. Confirm that the 'H' suffix indicates AEC-Q101 qualification if automotive grade is required. Ensure the ITO-220AB tube packing aligns with assembly requirements. Cross-reference the datasheet version for any updates to mechanical or electrical specifications before finalizing procurement.

Diode Arrays Selection Notes

Select this component for applications requiring 100 V blocking capability and 10 A continuous current handling. The ITO-220AB package provides robust thermal performance suitable for heatsink mounting. Consider the 50 ns reverse recovery time for switching frequency constraints. Verify that the dual die configuration meets the circuit topology requirements compared to single diode alternatives.

Diode Arrays Part Context

This part belongs to the HERF1001G–HERF1008G series of glass passivated high-efficient rectifiers. The series covers voltage ratings from 50 V to 1000 V while maintaining consistent current and package characteristics. The 'H' designation specifically denotes AEC-Q101 compliance, distinguishing it from standard industrial versions.

Diode Arrays Replacement Considerations

Direct substitutes include other parts within the HERF1001G series with equivalent 100 V ratings, such as HERF1002G. Verify pinout compatibility and thermal resistance values when replacing with components from different manufacturers.
