MBS6 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MBS6 is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications. This component operates at 600 V peak reverse voltage with an 800 mA average rectified current rating. The MBS6 is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), making it suitable for industrial and commercial electronic applications requiring rectification in power supply circuits.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the specified parameter ranges for this diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MBS6 bridge rectifier are identified based on strict electrical and mechanical parameter matching within the allowed specifications for single-phase bridge rectifier diodes. The substitution logic is based on the following key parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): Must equal or exceed 600 V
• Diode Type: Must be Single Phase
• Technology: Must be Standard
• Voltage - Forward (Vf) (Max) @ If: Must match 1 V @ 2 A specification
• Current - Reverse Leakage @ Vr: Must match 5 µA @ 600 V specification
• Operating Temperature Range: Must encompass -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Mounting Type: Must be Surface Mount
• Package / Case: Must be 4-BESOP (0.173", 4.40mm Width)
• Supplier Device Package: Must be MBS

Compliance Criteria:

• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level (MSL): Must be 1 (Unlimited)
• REACH Status: Must be REACH Unaffected

The RMB6S is identified as a parametric equivalent based on matching all mechanical, compliance, and core electrical parameters. The current rating difference (500 mA versus 800 mA) represents a parametric variation within the same product family and package specification.

Parameter Comparison

Engineering Selection Recommendations

MBS6 Primary Selection: The MBS6 is the direct manufacturer part number and primary component choice. It maintains active product status with full RoHS3 compliance and REACH unaffected designation. Current inventory of 1431 pieces supports immediate availability for production requirements.

RMB6S Parametric Equivalent: The RMB6S is a parametric equivalent substitute for the MBS6 bridge rectifier. Both components share identical voltage ratings (600 V peak reverse), forward voltage characteristics (1 V @ 2 A), reverse leakage specifications (5 µA @ 600 V), operating temperature range (-55°C to 150°C), and mechanical packaging (4-BESOP surface mount). Both maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating.

The RMB6S differs in average rectified current rating at 500 mA compared to the MBS6 at 800 mA. This lower current rating makes the RMB6S suitable for applications requiring reduced current capacity within the same voltage and thermal specifications. The RMB6S maintains active product status with significantly higher inventory availability (57100 pieces).

Compliance and Regulatory Alignment: Both the MBS6 and RMB6S meet identical regulatory requirements: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Both components are classified under HTSUS code 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can the RMB6S replace the MBS6 in all applications?

A: The RMB6S is electrically and mechanically compatible with the MBS6 for applications where the average rectified current requirement does not exceed 500 mA. The RMB6S maintains identical voltage ratings, forward voltage characteristics, reverse leakage specifications, operating temperature range, and package configuration. Applications requiring current capacity above 500 mA must use the MBS6 or equivalent 800 mA rated component.

Q: Are the MBS6 and RMB6S pin-compatible?

A: Yes. Both components use the 4-BESOP surface mount package with identical 0.173" (4.40mm) width specification. Pin configuration and PCB footprint requirements are identical between the two parts.

Q: What is the difference between MBS6 and RMB6S?

A: The primary difference is the average rectified current rating. The MBS6 is rated for 800 mA, while the RMB6S is rated for 500 mA. All other electrical parameters, including voltage ratings, forward voltage drop, reverse leakage, operating temperature range, and mechanical packaging are identical.

Q: Do both parts meet RoHS3 compliance?

A: Yes. Both the MBS6 and RMB6S are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level and REACH unaffected status.

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

A: Both the MBS6 and RMB6S operate across a junction temperature (TJ) range of -55°C to 150°C.

Q: Are there inventory considerations when selecting between MBS6 and RMB6S?

A: The RMB6S has significantly higher inventory availability at 57100 pieces compared to 1431 pieces for the MBS6. Component selection should prioritize the MBS6 for applications requiring 800 mA capacity, with RMB6S as an alternative for lower current applications where inventory availability is a consideration.
