ABS4H

Bridge Rectifier Overview

The ABS4H is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features an ABS-4 surface-mount package and is qualified to the AEC-Q101 automotive standard. The device supports a maximum average forward rectified current of 1A and a repetitive peak reverse voltage of 400V. It operates within a junction temperature range of -55°C to +175°C.

Bridge Rectifier Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for demanding environments
• High thermal performance enabling operation at elevated junction temperatures up to 175°C
• Glass passivated chip junctions provide protection against voltage spikes and improved stability

Bridge Rectifier Applications

• Automotive power supply circuits requiring high reliability
• General-purpose rectification in industrial electronics
• AC-to-DC conversion stages in compact surface-mount designs

Bridge Rectifier Procurement Notes

Verify the specific ordering suffixes on official datasheets or manufacturer documentation to confirm exact packaging configurations and material compliance details. Ensure that procurement channels source directly from authorized distributors to guarantee component authenticity and traceability throughout the supply chain.

Bridge Rectifier Selection Notes

Select this component when a 400V rating and 1A current capacity are required in a compact ABS-4 footprint. The AEC-Q101 qualification makes it suitable for automotive applications where extended temperature ranges and robustness are critical design constraints.

Bridge Rectifier Part Context

This part belongs to the ABS series of bridge rectifiers from Taiwan Semiconductor, designed for surface-mount technology. It shares the ABS-4 mechanical outline with other variants in the lineup but differs in electrical ratings and specific qualification statuses such as automotive certification.

Bridge Rectifier Replacement Considerations

Direct replacements must match the ABS-4 package, 1A current rating, and 400V reverse voltage. Verify that substitute components also meet AEC-Q101 requirements if the application mandates automotive-grade reliability.
