RS3B V6G Equivalent & Substitute Parts

Part Overview

The RS3B V6G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as discontinued at DiGi Electronics, indicating limited availability through standard distribution channels. The RS3B V6G maintains fast recovery characteristics with a reverse recovery time of 150 ns, suitable for standard rectification applications requiring moderate switching speeds. Identification of equivalent substitute parts is necessary due to product discontinuation status, which restricts procurement through primary distribution sources while functionally identical alternatives remain available in active production.

Substitute Part Grouping Explanation

Substitution of the RS3B V6G is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 3 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The RS3B base part number in Tape & Reel (TR) packaging represents the primary substitute, maintaining identical electrical specifications and compliance certifications while offering active product status and higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RS3B (Tape & Reel packaging) is the direct substitute for the RS3B V6G. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is product status: the RS3B V6G is discontinued at DiGi Electronics, while the RS3B maintains active production status with significantly higher inventory availability (2300 units versus 779 units).

Selection of the RS3B substitute is supported by:

1. Electrical Equivalence: All critical parameters including reverse voltage rating, rectified current capacity, reverse recovery time, and reverse leakage current are identical.

2. Mechanical Compatibility: Both components utilize the DO-214AB (SMC) surface mount package with identical footprints and mounting requirements.

3. Compliance Alignment: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

4. Availability: The RS3B substitute offers superior procurement reliability through active product status and higher stock levels across distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the RS3B substitute be used as a direct replacement for the RS3B V6G in existing designs?

A: Yes. The RS3B and RS3B V6G are electrically and mechanically equivalent. Both components share identical voltage ratings (100 V), current ratings (3 A), reverse recovery time (150 ns), and DO-214AB surface mount packaging. No circuit modifications are required.

Q: What is the difference between the RS3B V6G and RS3B part numbers?

A: The RS3B V6G and RS3B are the same component manufactured by Taiwan Semiconductor Corporation. The difference lies in packaging format and product status. The RS3B V6G is discontinued at DiGi Electronics, while the RS3B is supplied in Tape & Reel (TR) format with active production status.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the RS3B V6G and RS3B maintain identical RoHS3 compliance status and MSL 1 (Unlimited) moisture sensitivity rating. Both are REACH Unaffected and classified under ECCN EAR99.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range for both the RS3B V6G and RS3B is -55°C to 150°C, suitable for standard industrial and commercial applications.

Q: Does the Tape & Reel packaging of the RS3B substitute affect compatibility?

A: No. Tape & Reel (TR) packaging is a standard distribution format for surface mount components. The physical component dimensions, electrical characteristics, and DO-214AB package footprint remain identical. Tape & Reel format provides advantages for automated assembly processes.

Q: What is the reverse recovery time specification, and why is it important?

A: The reverse recovery time (trr) is 150 ns for both components. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking state. The 150 ns specification classifies these diodes as fast recovery devices, suitable for applications requiring moderate switching speeds in rectification circuits.

Q: What reverse leakage current should be expected at rated voltage?

A: Both the RS3B V6G and RS3B exhibit a reverse leakage current of 10 µA when 100 V reverse voltage is applied. This specification defines the maximum allowable leakage current under reverse bias conditions.
