RS3M V7G Equivalent & Substitute Parts

Part Overview

The RS3M V7G is a general-purpose rectifier diode rated for 1000 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. The fast recovery characteristic (≤500 ns) and compact SMC packaging make this diode suitable for standard rectification applications requiring moderate current handling in space-constrained designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3M V7G is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Maximum DC reverse voltage of 1000 V
• Current Rating: Average rectified current of 3 A
• Package Type: DO-214AB (SMC) surface mount configuration
• Reverse Recovery Time: 500 ns specification
• Reverse Leakage Current: 10 µA @ 1000 V
• Operating Temperature Range: -55°C to 150°C junction temperature
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part RS3M from SMC Diode Solutions meets all critical electrical and mechanical parameters. Both parts share identical voltage, current, package, and thermal specifications. The substitute maintains the same reverse recovery time and reverse leakage characteristics required for functional equivalence in rectification circuits.

Parameter Comparison

Engineering Selection Recommendations

The RS3M from SMC Diode Solutions is a direct functional equivalent to the discontinued RS3M V7G. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting identical environmental and regulatory requirements. The substitute part maintains active product status, ensuring continued availability for procurement and supply chain continuity.

Selection of the RS3M substitute is appropriate for applications requiring 1000 V, 3 A rectification in surface mount DO-214AB packaging. The electrical characteristics, thermal operating range, and compliance certifications are identical between the main part and substitute, supporting direct replacement in existing circuit designs without modification to PCB layouts or component footprints.

Frequently Asked Questions (FAQ)

Q: Can the RS3M substitute be used directly in place of the RS3M V7G?

A: Yes. Both parts share identical voltage ratings (1000 V), current ratings (3 A), package type (DO-214AB/SMC), reverse recovery time (500 ns), and operating temperature range (-55°C to 150°C). The PCB footprint and electrical performance are equivalent.

Q: What is the difference between the main part and the substitute?

A: The primary difference is manufacturer and product status. The RS3M V7G is discontinued; the RS3M substitute from SMC Diode Solutions is active. All electrical specifications and compliance certifications are identical.

Q: Are there any package or mounting differences?

A: No. Both parts use the DO-214AB (SMC) surface mount package. PCB layout and assembly processes remain unchanged.

Q: Does the substitute meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. Regulatory and environmental compliance is equivalent.

Q: What is the reverse recovery time specification?

A: Both the main part and substitute specify 500 ns reverse recovery time, classified as fast recovery for diodes with forward current greater than 200 mA.

Q: Is the reverse leakage current the same?

A: Yes. Both parts specify 10 µA reverse leakage current at 1000 V (or 1 kV) operating conditions.
