ABS4 REG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The ABS4 REG 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 is ROHS3 compliant. Equivalent and substitute parts are identified when identical electrical performance parameters and mechanical compatibility are maintained across different packaging configurations or automotive-grade variants.

Substitute Part Grouping Explanation

Substitute parts for the ABS4 REG are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Primary Substitution Criteria:

• Identical Voltage - Peak Reverse (Max): 400 V
• Identical Current - Average Rectified (Io): 800 mA
• Identical Voltage - Forward (Vf) (Max) @ If: 950 mV @ 400 mA
• Identical Current - Reverse Leakage @ Vr: 10 µA @ 400 V
• Identical Operating Temperature Range: -55°C ~ 150°C (TJ)
• Identical Mounting Type: Surface Mount
• Identical Package / Case: 4-SMD, Gull Wing
• Identical Diode Type: Single Phase
• Identical Technology: Standard

Secondary Considerations:

• Packaging format (Tape & Reel vs. standard packaging)
• Automotive-grade qualification (AEC-Q101)
• Product status (Active)

Parts meeting all primary criteria are classified as parametric equivalents and direct substitutes. The ABS4 and ABS4H variants differ only in packaging format and automotive qualification, while maintaining identical electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ABS4 REG, ABS4, and ABS4H—are Active product status and maintain identical electrical and thermal specifications. Selection between these parts is determined by application requirements and supply chain considerations:

ABS4 REG: Standard packaging format suitable for general industrial applications. ROHS3 compliant with unlimited moisture sensitivity rating.

ABS4: Identical electrical specifications to ABS4 REG with Tape & Reel packaging format. Suitable for high-volume automated assembly processes. ROHS3 compliant with unlimited moisture sensitivity rating.

ABS4H: Automotive-grade variant with AEC-Q101 qualification. Tape & Reel packaging format. Maintains identical electrical specifications while meeting automotive industry standards. ROHS3 compliant with unlimited moisture sensitivity rating. Appropriate for automotive and mission-critical applications requiring automotive-grade component certification.

All parts are manufactured by Taiwan Semiconductor Corporation and are REACH Unaffected with EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can ABS4 REG be directly replaced with ABS4?

A: Yes. Both parts have identical electrical parameters, operating temperature range, and package configuration (4-SMD, Gull Wing). The primary difference is packaging format: ABS4 REG uses standard packaging while ABS4 uses Tape & Reel format. Electrical performance and mechanical compatibility are equivalent.

Q: What is the difference between ABS4 and ABS4H?

A: ABS4 and ABS4H have identical electrical specifications and package types. ABS4H includes automotive-grade classification and AEC-Q101 qualification, making it suitable for automotive applications. Both use Tape & Reel packaging format.

Q: Is ABS4H suitable for automotive applications?

A: Yes. ABS4H carries AEC-Q101 qualification and automotive-grade designation, meeting automotive industry standards. It maintains the same electrical performance as the standard variants while satisfying automotive qualification requirements.

Q: What does Tape & Reel packaging mean?

A: Tape & Reel (TR) packaging is a continuous strip format used for automated assembly processes. Components are mounted on a carrier tape with a cover tape, wound on a reel for high-volume production. This differs from standard packaging, which may use alternative formats.

Q: Are all three parts ROHS3 compliant?

A: Yes. ABS4 REG, ABS4, and ABS4H are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Can these parts be used interchangeably in circuit design?

A: Yes, provided the application does not require automotive-grade certification. For automotive applications, ABS4H is the appropriate selection. For standard industrial applications, ABS4 REG and ABS4 are electrically and mechanically interchangeable.

Q: What is the operating temperature range for these bridge rectifiers?

A: All three parts operate across -55°C to 150°C junction temperature range, suitable for industrial and automotive temperature environments.
