ABS15MHREG Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The ABS15MHREG is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 1 kV peak reverse voltage and 1.5 A 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 supply circuits, battery charging systems, and AC-to-DC conversion applications where reliable full-wave rectification is required. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the ABS15MHREG are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 1 kV
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 1.5 A
• Voltage - Forward (Vf) (Max): Equal to or less than 1 V at rated current
• Current - Reverse Leakage @ Vr: Equal to or less than 5 µA @ 1000 V
• Operating Temperature Range: Must encompass or equal the -55°C to 150°C specification

All identified substitute parts meet these criteria and are classified as parametric equivalents suitable for direct replacement in applications designed for the ABS15MHREG.

Parameter Comparison

Engineering Selection Recommendations

ABS15MH (Taiwan Semiconductor Corporation)

The ABS15MH is a direct parametric equivalent to the ABS15MHREG, manufactured by the same supplier. Both parts share identical electrical specifications, automotive-grade classification, and AEC-Q101 qualification. The primary distinction is packaging format: ABS15MH is supplied in Tape & Reel (TR) configuration, whereas ABS15MHREG is supplied in standard packaging. This substitute is suitable for applications requiring automotive-grade reliability and qualification compliance. The ABS15MH maintains the same operating temperature range (-55°C to 150°C) and all electrical parameters.

ABS15M (Diotec Semiconductor)

The ABS15M is a parametric equivalent with a higher current rating of 2 A, compared to the 1.5 A specification of the ABS15MHREG. This part is suitable for applications where the 1.5 A requirement can accommodate higher current capacity. The forward voltage specification is 1.1 V @ 2 A, which is within acceptable tolerance for standard bridge rectifier applications. The operating temperature range is -50°C to 150°C, which covers the upper specification of the main part but has a narrower lower temperature limit. This substitute is RoHS3 compliant and suitable for general industrial applications. Automotive-grade qualification is not specified for this part.

DB157S (MDD)

The DB157S is a parametric equivalent manufactured by MDD with identical electrical specifications to the ABS15MHREG: 1 kV peak reverse voltage, 1.5 A average rectified current, and 1 V forward voltage. This part features superior reverse leakage characteristics at 1 µA @ 1000 V, compared to 5 µA for the main part. The operating temperature range is -55°C to 150°C, matching the main part specification. The DB157S is RoHS3 compliant and suitable for applications requiring low reverse leakage performance. Automotive-grade qualification and AEC-Q101 certification are not specified for this part.

Frequently Asked Questions (FAQ)

Q: Can ABS15M be used as a direct replacement for ABS15MHREG in all applications?

A: The ABS15M is electrically compatible with the ABS15MHREG for applications operating at or below 1.5 A. The higher current rating of 2 A provides additional design margin. However, the ABS15M does not carry automotive-grade classification or AEC-Q101 qualification. Applications requiring automotive compliance must use ABS15MH or ABS15MHREG. The operating temperature lower limit of -50°C (versus -55°C for the main part) may be a constraint in extreme cold-temperature environments.

Q: What is the difference between ABS15MH and ABS15MHREG?

A: The ABS15MH and ABS15MHREG are electrically and mechanically identical. Both are manufactured by Taiwan Semiconductor Corporation with identical specifications, automotive-grade classification, and AEC-Q101 qualification. The primary difference is packaging format: ABS15MH is supplied in Tape & Reel (TR) configuration for automated assembly, while ABS15MHREG is supplied in standard packaging. Selection between these parts depends on procurement and assembly requirements.

Q: Is DB157S suitable for automotive applications?

A: The DB157S meets the electrical and mechanical requirements for the ABS15MHREG application. However, automotive-grade classification and AEC-Q101 qualification are not specified for the DB157S. Applications requiring automotive compliance and qualification certification must use ABS15MH or ABS15MHREG. The DB157S is suitable for industrial and consumer applications where automotive qualification is not required.

Q: What are the package compatibility considerations?

A: All substitute parts (ABS15MH, ABS15M, and DB157S) use the same 4-SMD, Gull Wing package configuration as the ABS15MHREG. This ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes. No design modifications are required for package accommodation.

Q: How do reverse leakage specifications compare among the substitutes?

A: The ABS15MHREG, ABS15MH, and ABS15M all specify 5 µA reverse leakage @ 1000 V. The DB157S specifies 1 µA @ 1000 V, representing superior leakage performance. For applications sensitive to reverse leakage current, the DB157S provides enhanced performance characteristics. This difference does not affect standard rectification applications but may be relevant in precision measurement or high-impedance circuits.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all identified substitute parts (ABS15MH, ABS15M, and DB157S) are RoHS3 compliant, matching the compliance status of the ABS15MHREG. This ensures compatibility with environmental and regulatory requirements for electronic components.
