ABS8H

Bridge Rectifier Overview

The ABS8H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an 800 V maximum repetitive reverse voltage and an 8 A average forward rectified current rating. The device utilizes standard silicon technology and is housed in an ABS surface-mount package with a 4-SMD,鸥翼 (gull-wing) configuration. It operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage of 1.7 V at 8 A and a maximum reverse leakage current of 1 µA at 800 V.

Bridge Rectifier Procurement Notes

Verify the manufacturer part number ABS8H against official Taiwan Semiconductor documentation to confirm specifications. Ensure the ordering suffix matches the required packaging format, such as tape and reel or cut tape, as indicated in the datasheet. Confirm RoHS compliance status if environmental regulations apply to the end product.

Bridge Rectifier Selection Notes

Select this component when a surface-mount single-phase bridge rectifier with 800 V blocking voltage and 8 A continuous current is required. Compare the forward voltage drop and reverse leakage current against circuit efficiency requirements. Ensure the PCB footprint accommodates the 4-SMD gull-wing package dimensions specified in the mechanical data.

Bridge Rectifier Part Context

This component belongs to the ABS series of surface-mount bridge rectifiers from Taiwan Semiconductor. These devices are designed for high-reliability applications requiring compact form factors. The ABS8H specifically addresses needs for medium-current rectification in space-constrained electronic designs.

Bridge Rectifier Replacement Considerations

Check for direct pin-compatible substitutes from other manufacturers offering identical 8 A / 800 V ratings in ABS packages. Verify that any replacement maintains the same forward voltage characteristics and thermal performance to ensure circuit compatibility.
