ABS4HREG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The ABS4HREG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications. This component operates at 400 V peak reverse voltage with an 800 mA average rectified current rating. The part is classified as Active product status and carries automotive-grade qualification under AEC-Q101 standard. Alternative equivalent parts are necessary to address inventory availability, packaging format requirements, or supply chain considerations while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ABS4HREG are determined by equivalence across the following critical parameters:

• Voltage Rating: Peak reverse voltage of 400 V
• Current Rating: Average rectified current of 800 mA
• Forward Voltage Characteristic: 950 mV maximum at 400 mA
• Reverse Leakage: 10 µA at 400 V
• Temperature Operating Range: -55°C to 150°C junction temperature
• Mounting Configuration: Surface mount technology with 4-SMD, Gull Wing package
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute parts ABS4H and ABS4 share identical electrical specifications and mechanical mounting requirements with the ABS4HREG. The primary distinction between these parts lies in packaging format (Tape & Reel versus individual packaging) and inventory availability. Both substitute parts maintain the same base product number (ABS4) and are manufactured by Taiwan Semiconductor Corporation.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ABS4HREG, ABS4H, and ABS4—are Active product status components manufactured by Taiwan Semiconductor Corporation with identical electrical and mechanical specifications. The ABS4HREG and ABS4H both carry automotive-grade classification with AEC-Q101 qualification, meeting stringent automotive industry standards. The ABS4 variant does not specify automotive grade or AEC-Q101 qualification in the provided parameters.

For applications requiring automotive-grade compliance and AEC-Q101 qualification, either ABS4HREG or ABS4H are appropriate selections. The ABS4 part is suitable for non-automotive applications where automotive qualification is not a requirement.

All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for global supply chains. The primary differentiation between parts is packaging format: ABS4HREG is supplied in individual packaging, while ABS4H and ABS4 are supplied in Tape & Reel format. Inventory availability differs across the three variants, with ABS4 showing the highest stock level at 4300 pieces, ABS4H at 6139 pieces, and ABS4HREG at 795 pieces.

Frequently Asked Questions (FAQ)

Q: Can ABS4 be used as a direct substitute for ABS4HREG in automotive applications?

A: The ABS4 shares identical electrical and mechanical parameters with ABS4HREG. However, ABS4 does not carry automotive-grade designation or AEC-Q101 qualification in the provided specifications. For automotive applications requiring these certifications, ABS4H is the appropriate substitute.

Q: What is the difference between ABS4HREG and ABS4H?

A: Both parts are automotive-grade with AEC-Q101 qualification and identical electrical specifications. The primary difference is packaging format: ABS4HREG is supplied in individual packaging, while ABS4H is supplied in Tape & Reel format. Both are Active product status.

Q: Are all three parts compatible with the same PCB layout and assembly process?

A: Yes. All three parts share identical mounting type (Surface Mount), package configuration (4-SMD, Gull Wing), and electrical characteristics. PCB layout and assembly processes are compatible across all three variants.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under normal storage conditions without requiring special moisture control measures.

Q: Can these parts be used interchangeably in terms of electrical performance?

A: Yes. All three parts have identical voltage ratings (400 V peak reverse), current ratings (800 mA average rectified), forward voltage characteristics (950 mV @ 400 mA), reverse leakage (10 µA @ 400 V), and operating temperature range (-55°C to 150°C).

Q: Which part should be selected for high-volume production?

A: ABS4 offers the highest inventory availability at 4300 pieces in Tape & Reel format, making it suitable for high-volume production runs. For automotive applications, ABS4H provides both high availability (6139 pieces) and required automotive-grade qualification.
