HER108G

Single Diodes Overview

The HER108G is a silicon rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single element configuration with a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 1000 V. The device utilizes a DO-204AL (DO-41) axial leaded package constructed from plastic epoxy molding compound rated UL 94V-0 for flame retardancy. Electrical characteristics include glass passivation for junction protection, low forward voltage drop, and high surge current capability. The component operates within a temperature range of -55 °C to +150 °C and complies with RoHS directives.

Single Diodes Procurement Notes

Verify the specific suffix on the ordering code to confirm compliance requirements. Suffixes such as 'H' indicate AEC-Q101 qualification and specific whisker test compliance, while 'G' denotes halogen-free green compound packaging. Confirm the packing code matches the required reel specifications before procurement.

Single Diodes Selection Notes

Select this component for general-purpose rectification where high reliability and thermal stability are required. Ensure the circuit's peak inverse voltage does not exceed the 1000 V rating. Verify that the operating ambient temperature remains within the specified -55 °C to +150 °C range to maintain performance integrity.

Single Diodes Part Context

This part belongs to the HER10x series of high-efficiency rectifiers from Taiwan Semiconductor. The series covers various reverse voltage ratings from 50 V to 1000 V, sharing common mechanical data and package styles like DO-41. These components are designed for industrial and consumer electronics requiring robust power conversion capabilities.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-41 packaged 1A 1000V rectifiers. Verify pinout compatibility and ensure equivalent electrical parameters, specifically forward voltage and reverse recovery time, match the original design requirements.
