ABS8HREG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The ABS8HREG is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 800 V peak reverse voltage and 800 mA average rectified current. This component is classified as an active product with automotive-grade qualification (AEC-Q101) and is RoHS3 compliant. Bridge rectifiers of this specification are essential in power conversion applications requiring full-wave rectification at moderate voltage and current levels. Substitute parts are identified to address inventory availability, lead time requirements, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ABS8HREG are identified based on strict electrical and mechanical parameter matching within the bridge rectifier diode category. The substitution logic is governed by the following key parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): 800 V (exact match required)
• Diode Type: Single Phase (exact match required)
• Technology: Standard (exact match required)
• Operating Temperature Range: -55°C to 150°C (exact match required)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, Gull Wing (exact match required)
• Supplier Device Package: ABS (exact match required)

Current Rating Consideration:

• Current - Average Rectified (Io): Substitute parts must meet or exceed the 800 mA requirement of the main part

Compliance & Certification:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Status: REACH Unaffected (required)

Parts meeting all electrical, mechanical, and compliance criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

ABS8H Substitution: The ABS8H is a direct parametric equivalent to the ABS8HREG. Both components share identical electrical specifications (800 V peak reverse voltage, 800 mA average rectified current, 950 mV forward voltage at 400 mA, and 10 µA reverse leakage at 800 V). Both are manufactured by Taiwan Semiconductor Corporation with automotive-grade qualification (AEC-Q101) and are RoHS3 compliant. The ABS8H is supplied in Tape & Reel packaging and maintains the same 4-SMD Gull Wing package configuration. This substitute is suitable for direct replacement in all applications where the ABS8HREG is specified.

ABS8 Substitution: The ABS8 meets the core electrical and mechanical compatibility criteria (800 V peak reverse voltage, single-phase diode type, standard technology, surface mount configuration, 4-SMD Gull Wing package, RoHS3 compliance, and MSL 1). However, the ABS8 is rated for 41 mA average rectified current, which is significantly below the 800 mA requirement of the main part. The ABS8 is manufactured by MDD and does not carry automotive-grade qualification or AEC-Q101 certification. This substitute is not suitable for applications requiring the full 800 mA current rating or automotive-grade compliance.

Selection Basis:

• For automotive applications or designs requiring AEC-Q101 qualification: Use ABS8H
• For non-automotive applications with reduced current requirements (≤41 mA): ABS8 may be considered with design review
• Packaging preference (Tape & Reel vs. bulk): Both ABS8H and ABS8 are available in Tape & Reel format

Frequently Asked Questions (FAQ)

Q: Can the ABS8 be used as a substitute for the ABS8HREG in a 800 mA application?

A: No. The ABS8 is rated for 41 mA average rectified current, which does not meet the 800 mA requirement of the ABS8HREG. Using an undersized component will result in thermal stress, reduced reliability, and potential component failure. The ABS8H is the appropriate substitute for full-current applications.

Q: Are the ABS8HREG and ABS8H electrically interchangeable?

A: Yes. The ABS8HREG and ABS8H are parametric equivalents with identical electrical specifications: 800 V peak reverse voltage, 800 mA average rectified current, 950 mV forward voltage at 400 mA, and 10 µA reverse leakage at 800 V. Both are automotive-grade (AEC-Q101) and RoHS3 compliant. They are direct substitutes.

Q: What is the difference between the ABS8HREG and ABS8H packaging?

A: The ABS8HREG packaging type is not specified in the component data. The ABS8H is supplied in Tape & Reel (TR) format. Both components use the same 4-SMD Gull Wing package configuration and are suitable for automated assembly processes.

Q: Does the ABS8 carry automotive qualification?

A: No. The ABS8 does not have automotive-grade designation or AEC-Q101 qualification. It is suitable only for non-automotive applications. For automotive or safety-critical applications, use the ABS8H, which carries AEC-Q101 certification.

Q: Are all three parts (ABS8HREG, ABS8H, ABS8) RoHS3 compliant?

A: Yes. All three parts are RoHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the primary reason to substitute the ABS8HREG?

A: Substitution is typically driven by inventory availability, lead time requirements, or packaging format preferences. The ABS8H is the recommended substitute for direct replacement. The ABS8 is suitable only for applications with significantly lower current requirements (≤41 mA) and non-automotive use cases.

Q: Can the ABS8HREG be used in place of the ABS8H?

A: Yes. The ABS8HREG and ABS8H are parametric equivalents with identical electrical and mechanical specifications. Either part can be used interchangeably in designs specifying either part number.
