RS3D V7G Equivalent & Substitute Parts

Part Overview

The RS3D V7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 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 substitute parts for ongoing design requirements and procurement needs. Active equivalent and substitute parts are available from the same and alternative manufacturers to maintain design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS3D V7G are identified based on strict electrical and mechanical parameter matching within the allowed specifications for general-purpose rectifier diodes. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)
• Operating Temperature Range: Must encompass or exceed -55°C ~ 150°C

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-214AB, SMC
• Supplier Device Package: DO-214AB (SMC)

Compliance Requirements:

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

Parts meeting all electrical, mechanical, and compliance criteria are classified as direct substitutes. Parts with enhanced specifications (higher voltage ratings, lower reverse recovery times, improved temperature ranges, or lower reverse leakage currents) remain functionally compatible within the RS3D V7G application envelope.

Parameter Comparison

Engineering Selection Recommendations

RS3D (Direct Equivalent): The RS3D from Taiwan Semiconductor Corporation is the direct equivalent to the RS3D V7G. This part maintains identical electrical specifications and packaging, with the primary distinction being product status: the RS3D is currently active with 3192 pieces in stock, compared to the discontinued RS3D V7G. This part is the preferred selection for direct replacement in existing designs.

MURS320-M3/9AT (Substitute): The MURS320-M3/9AT from Vishay General Semiconductor - Diodes Division is a functionally compatible substitute that meets all electrical and mechanical requirements. This part demonstrates enhanced performance characteristics: reverse recovery time of 35 ns (compared to 150 ns), lower reverse leakage current of 5 µA (compared to 10 µA), and an extended operating temperature range of -65°C ~ 175°C (compared to -55°C ~ 150°C). The MURS320-M3/9AT is currently active with 933 pieces in stock. Selection of this substitute is appropriate when improved performance specifications provide design benefits or when supply availability of the direct equivalent is constrained.

Both substitute options maintain ROHS3 compliance, MSL 1 rating, and identical surface mount DO-214AB packaging, ensuring mechanical and environmental compatibility with the original RS3D V7G design.

Frequently Asked Questions (FAQ)

Q: Can the RS3D be used as a direct replacement for the RS3D V7G?

A: Yes. The RS3D is electrically and mechanically identical to the RS3D V7G, with matching voltage ratings (200 V), current ratings (3 A), reverse recovery time (150 ns), and package type (DO-214AB, SMC). The primary difference is product status: RS3D is active, while RS3D V7G is discontinued.

Q: What are the key differences between the RS3D and MURS320-M3/9AT?

A: Both parts meet the core electrical requirements of 200 V reverse voltage and 3 A current rating in DO-214AB packaging. The MURS320-M3/9AT offers improved performance: reverse recovery time of 35 ns (versus 150 ns), reverse leakage current of 5 µA (versus 10 µA), and extended temperature range to -65°C ~ 175°C (versus -55°C ~ 150°C). The manufacturer differs: Taiwan Semiconductor Corporation for RS3D versus Vishay for MURS320-M3/9AT.

Q: Are all substitute parts in the same package?

A: Yes. The RS3D, RS3D V7G, and MURS320-M3/9AT all use the DO-214AB (SMC) surface mount package. No PCB layout modifications are required when substituting between these parts.

Q: Do all parts meet RoHS and environmental compliance requirements?

A: Yes. The RS3D V7G, RS3D, and MURS320-M3/9AT are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are REACH unaffected and classified under ECCN EAR99.

Q: Which substitute should be selected for new designs?

A: For new designs, the RS3D is the preferred selection as the direct equivalent with active product status and established supply. The MURS320-M3/9AT is appropriate when the enhanced performance specifications (faster recovery time, lower leakage current, wider temperature range) provide design advantages or when supply constraints necessitate an alternative source.

Q: Can the MURS320-M3/9AT be used in applications originally designed for the RS3D V7G?

A: Yes. The MURS320-M3/9AT meets or exceeds all electrical specifications required by the RS3D V7G. The improved reverse recovery time and lower leakage current represent performance enhancements that maintain full compatibility within the original application envelope.
