Diode Arrays Procurement Notes

Verify the specific suffix 'H' confirms AEC-Q101 automotive qualification status. Confirm the 'G' suffix indicates green compound packaging that is halogen-free per IEC 61249-2-21 definitions. Ensure the ordering code matches the required voltage rating within the 50V to 1000V series range. Check packing specifications for tube quantities as listed in official documentation.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency and low thermal resistance in a through-hole package. The dual common cathode design simplifies circuit layouts for synchronous rectification or bridge configurations. Consider the 1.5 °C/W junction-to-case thermal resistance for heat dissipation planning. Verify compatibility with operating temperatures up to 150°C.

Diode Arrays Part Context

This part belongs to the HER1001G–HER1008G series of glass passivated high-efficient rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V in a single TO-220AB form factor. The 'H' designation specifically denotes AEC-Q101 qualification, distinguishing it from standard industrial versions.

Diode Arrays Replacement Considerations

Direct substitutes include other AEC-Q101 qualified dual common cathode rectifiers in TO-220AB packages with matching 10A current and 50V reverse voltage ratings. Verify equivalent forward voltage and reverse recovery time specifications to ensure circuit performance parity.
