HERF1001GH

Diode Arrays Overview

The HERF1001GH is a high-efficiency rectifier from Taiwan Semiconductor, rated for 50V repetitive peak reverse voltage and 10A average forward current. It utilizes an ITO-220AB package with dual dies configuration. The component features a maximum non-repetitive surge forward current of 125A and operates within a junction temperature range of -55°C to +150°C. Electrical characteristics include a typical forward voltage of 1.0V at 5A, a reverse current of 10µA at 25°C, and a reverse recovery time of 50ns. The suffix 'H' indicates AEC-Q101 qualification.

Diode Arrays Feature Summary

• High efficiency operation with low forward voltage drop
• High current and surge current capability
• Glass passivated chip junction for reliability
• Compliant with RoHS Directive and halogen-free standards

Diode Arrays Applications

• DC to DC converter circuits
• Switching mode converters and inverters
• Freewheeling applications

Diode Arrays Procurement Notes

Verify the specific ordering code matches the required voltage rating and package type. Confirm that the 'H' suffix denotes AEC-Q101 automotive qualification if required by the design specifications. Ensure the packing quantity aligns with production needs, as standard tubes contain 50 units per tube. Cross-reference the date code and factory code on the marking diagram for traceability purposes during quality assurance checks.

Diode Arrays Selection Notes

Select this component for designs requiring robust performance in switching power supplies and inverters. The ITO-220AB package provides adequate thermal management with a junction-to-case thermal resistance of 3°C/W. Consider the 125A surge capability for handling transient loads. The AEC-Q101 qualification makes it suitable for automotive-grade applications where high reliability and extended temperature operation are critical requirements.

Diode Arrays Part Context

This device belongs to the HERF1001G–HERF1008G series of high-efficient rectifiers manufactured by Taiwan Semiconductor. The series covers voltage ratings from 50V to 1000V while maintaining a consistent 10A forward current rating across all variants. The HERF1001GH specifically represents the 50V variant within this lineup, distinguished by its automotive qualification status indicated by the 'H' suffix in the part number.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include HERF1001G (non-automotive) or other voltage variants like HERF1002G if higher reverse voltage is needed. Verify pinout compatibility and thermal resistance specifications when replacing with components from other manufacturers.
