HER1004GH

Diode Arrays Overview

The HER1004GH is a glass passivated high-efficiency rectifier diode array manufactured by Taiwan Semiconductor. It features a dual common cathode configuration housed in a TO-220AB package. The device supports a maximum repetitive peak reverse voltage of 300V and an average forward rectified current of 10A. Key electrical characteristics include a maximum non-repetitive peak surge current of 125A, a typical reverse recovery time of 80ns, and a maximum instantaneous forward voltage of 1.7V at rated current.

Diode Arrays Feature Summary

• Glass passivated junction for enhanced reliability and environmental resistance
• High efficiency design with low forward voltage drop to minimize power loss
• Capable of handling high surge currents during transient events
• Halogen-free construction compliant with IEC 61249-2-21 definitions

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free wheeling applications in motor drives
• Polarity protection circuits
• General purpose rectification in industrial power supplies

Diode Arrays Procurement Notes

Verify the specific suffix on the packing code to confirm material composition and qualification status. Suffixes such as 'G' indicate halogen-free green compound, while 'H' may denote AEC-Q101 automotive qualification. Ensure the ordering part number matches the required package variant and regulatory compliance standards for your specific manufacturing environment.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or bridge-less topologies. The TO-220AB package provides robust thermal dissipation for 10A continuous operation. Consider the 80ns reverse recovery time for high-frequency switching applications where standard recovery times might cause excessive losses or noise.

Diode Arrays Part Context

This part belongs to the HER series of glass passivated high-efficient rectifiers from Taiwan Semiconductor. The series covers various voltage and current ratings across different packages including DO-15, DO-201AD, and TO-220AB. The HER1004GH specifically addresses the need for medium-voltage, high-current dual diode solutions in compact through-hole formats.

Diode Arrays Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers' 10A, 300V dual common cathode diodes in TO-220AB packages only if electrical parameters match exactly.
