RS3A V7G Equivalent & Substitute Parts

Part Overview

The RS3A V7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 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, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. The part operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 150 ns, making it suitable for standard rectification circuits requiring moderate current handling and voltage blocking capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3A V7G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 50 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 150 ns maximum
• Current - Reverse Leakage @ Vr: 10 µA @ 50 V maximum

Mechanical Equivalence Criteria:

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

Compliance Criteria:

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

Parts meeting all criteria above are classified as direct substitutes. The RS3A from Taiwan Semiconductor Corporation satisfies all substitution parameters and is available in active product status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RS3A manufactured by Taiwan Semiconductor Corporation is the direct substitute for the discontinued RS3A V7G. Both parts share identical electrical specifications, mechanical packaging, and operating parameters. The substitute part maintains active product status with significantly higher inventory availability (4,300 pieces in stock versus 977 pieces for the main part).

Both parts comply with ROHS3 requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special moisture control measures are required during storage or handling. The substitute part provides complete functional and physical compatibility for direct replacement in existing designs and production environments.

Selection of the RS3A substitute is based on parameter equivalence, active availability, and regulatory compliance alignment with the discontinued RS3A V7G.

Frequently Asked Questions (FAQ)

Q: Can the RS3A substitute be used as a direct replacement for the RS3A V7G in existing circuit designs?

A: Yes. The RS3A meets all electrical and mechanical equivalence criteria. Both parts feature identical voltage ratings (50 V), current ratings (3 A), reverse recovery time (150 ns), reverse leakage current (10 µA @ 50 V), and package configuration (DO-214AB SMC). No circuit modifications are required.

Q: Are there any differences in thermal performance between the RS3A V7G and the RS3A substitute?

A: Both parts operate across the same junction temperature range (-55°C to 150°C). No thermal performance differences exist between the two parts.

Q: What is the significance of the DO-214AB (SMC) package designation?

A: DO-214AB is a surface mount package standard for rectifier diodes. The SMC designation confirms surface mount compatibility. Both the main part and substitute use this identical package, ensuring mechanical and electrical compatibility on PCB layouts without modification.

Q: Does the RS3A substitute require different handling or storage procedures compared to the RS3A V7G?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity classification, indicating unlimited shelf life without special moisture control measures. Identical handling and storage procedures apply to both parts.

Q: What is the forward voltage specification for the RS3A substitute?

A: The RS3A substitute specifies a maximum forward voltage of 1.3 V at 3 A forward current. This parameter was not provided for the RS3A V7G main part.

Q: Are both parts RoHS compliant?

A: Yes. Both the RS3A V7G and the RS3A substitute carry ROHS3 Compliant status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
