HER1005GH

Diode Arrays Overview

The HER1005GH is a fast recovery rectifier diode array manufactured by Taiwan Semiconductor Corporation. It features a dual common cathode configuration housed in a TO-220AB (TO-220-3) through-hole package. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 10 A per diode. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 400 V, a forward voltage drop of 1.3 V at 5 A, and a reverse recovery time of 50 ns. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 automotive qualification.

Diode Arrays Procurement Notes

Verify the specific packing code prefix when ordering. Prefix 'H' indicates compliance with JESD 201 Class 1 whisker test requirements. Confirm RoHS3 status and REACH compliance through official datasheets. Ensure the TO-220AB package dimensions match your PCB footprint constraints before finalizing procurement.

Diode Arrays Selection Notes

Select this component for designs requiring 10 A continuous current handling with fast switching speeds. The 400 V rating suits medium-voltage DC systems. Compare thermal resistance values against your heatsinking strategy. Verify that the 50 ns reverse recovery time meets your circuit's EMI and efficiency targets compared to standard recovery alternatives.

Diode Arrays Part Context

This part belongs to the HER10xxG series of high-efficiency rectifiers from Taiwan Semiconductor. The series offers various voltage ratings while maintaining consistent current and package specifications. The HER1005GH specifically addresses the 400 V segment, providing a balance between blocking capability and switching speed for industrial and automotive electronics.

Diode Arrays Replacement Considerations

Direct substitutes may include other 10 A, 400 V, dual common cathode fast recovery diodes in TO-220 packages. Verify pinout compatibility and thermal characteristics. Check if alternative manufacturers offer equivalent AEC-Q101 certification if automotive qualification is mandatory.
