HER1001G

Diode Arrays Overview

The HER1001G is a dual common cathode fast recovery rectifier from Taiwan Semiconductor, rated for a repetitive peak reverse voltage of 50 V and an average forward current of 10 A. It features a maximum surge current capability of 125 A and operates within a junction temperature range of -55°C to +150°C. The device utilizes a TO-220AB through-hole package with a typical junction-to-case thermal resistance of 1.5 °C/W. Electrical characteristics include a maximum forward voltage of 1.0 V at 5 A, a reverse leakage current of 10 µA at 25°C, and a reverse recovery time of 50 ns.

Diode Arrays Feature Summary

• Glass passivated chip junction ensures high reliability and low power loss

• Freewheeling applications

Diode Arrays Procurement Notes

Verify the specific part number suffix when ordering. The standard designation HER1001G indicates a tube packing format containing 50 units per tube. If automotive qualification under AEC-Q101 is required, confirm that the 'H' suffix is included in the ordering code (HER1001GH). Ensure the procurement documentation matches the requested packaging type and compliance status.

Diode Arrays Selection Notes

Select this component for circuits requiring a 50 V blocking voltage and 10 A continuous current handling in a dual configuration. The TO-220AB package provides adequate thermal dissipation for many power supply designs. Consider the 50 ns reverse recovery time for switching frequencies compatible with fast recovery rectifiers. Verify that the application does not exceed the 125 A non-repetitive surge limit.

Diode Arrays Part Context

This device belongs to the HER10xG series, which covers voltage ratings from 50 V to 1000 V across eight variants. All members share identical physical dimensions, pinouts, and thermal characteristics in the TO-220AB package. The series is designed as a high-efficiency rectifier solution for general-purpose power conversion applications requiring robust performance.

Diode Arrays Replacement Considerations

Direct substitutes within the same family include HER1002G through HER1008G, provided the circuit voltage rating accommodates their higher reverse voltage capabilities. Automotive-grade equivalents are available by adding the 'H' suffix to any variant in the series.
