RS3G V7G Equivalent & Substitute Parts

Part Overview

The RS3G V7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage with 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 production and repair applications. The part demonstrates fast recovery characteristics with a reverse recovery time of 150 ns, suitable for standard rectification circuits requiring moderate voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3G V7G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Maximum DC reverse voltage of 400 V
• Current Rating: Average rectified current of 3 A
• Reverse Recovery Time: 150 ns (fast recovery classification)
• Reverse Leakage Current: 10 µA at 400 V
• Package Type: DO-214AB (SMC) surface mount configuration
• Temperature Range: Operating junction temperature from -55°C to 150°C
• Compliance: ROHS3 compliance and REACH unaffected status

Substitute parts must match all electrical parameters and physical package specifications. Packaging format (Tape & Reel versus bulk) does not affect electrical equivalence but impacts procurement and assembly logistics.

Parameter Comparison

Engineering Selection Recommendations

The RS3G (Tape & Reel packaging) serves as a direct electrical and mechanical equivalent to the RS3G V7G. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications across all critical parameters: 400 V reverse voltage, 3 A average rectified current, 150 ns reverse recovery time, and 10 µA reverse leakage current at rated voltage.

The primary distinction is product status: the RS3G V7G is discontinued at DiGi Electronics, while the RS3G maintains active status with higher inventory availability (1580 pieces in stock versus 776 pieces for the discontinued variant). Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The packaging format difference (Tape & Reel for the substitute versus unspecified for the main part) does not affect circuit performance or PCB assembly compatibility. Selection of the RS3G as a substitute is appropriate for applications requiring the specified electrical and thermal characteristics within the DO-214AB surface mount package.

Frequently Asked Questions (FAQ)

Q: Are the RS3G V7G and RS3G electrically identical?

A: Yes. Both parts share identical electrical specifications: 400 V maximum reverse voltage, 3 A average rectified current, 150 ns reverse recovery time, and 10 µA reverse leakage current at 400 V. Both operate across the same temperature range (-55°C to 150°C) and employ standard rectifier technology.

Q: What is the difference between the RS3G V7G and RS3G?

A: The RS3G V7G is discontinued at DiGi Electronics, while the RS3G maintains active product status. The RS3G is supplied in Tape & Reel packaging format. All electrical and mechanical parameters are identical.

Q: Can the RS3G be used as a direct replacement in existing designs?

A: Yes. The RS3G is a direct substitute for the RS3G V7G. It shares the same DO-214AB (SMC) surface mount package, electrical ratings, and thermal specifications. No circuit modifications are required.

Q: Does packaging format affect circuit performance?

A: No. Tape & Reel packaging is a procurement and assembly format that does not alter the electrical characteristics or performance of the diode. The component itself is identical regardless of packaging format.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the RS3G V7G and RS3G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the reverse recovery time significance?

A: The 150 ns reverse recovery time classifies both parts as fast recovery diodes. This parameter determines switching speed in rectification circuits and is identical between the main part and substitute.
