SMCG60A-M3/9AT Equivalent & Substitute Parts

Part Overview

The SMCG60A-M3/9AT is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface-mount component is designed for general-purpose transient voltage protection applications. The device is currently in active production status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging configurations are required, or when sourcing from different inventory batches is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCG60A-M3/9AT is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 60V (Typ)
• Voltage - Breakdown: 66.7V (Min)
• Voltage - Clamping: 96V (Max @ Ipp)
• Current - Peak Pulse: 15.5A (10/1000µs)
• Power - Peak Pulse: 1500W
• Package / Case: DO-215AB, SMC Gull Wing
• Mounting Type: Surface Mount
• Unidirectional Channels: 1

The substitute part SMCG60A-E3/57T meets all these criteria identically. The difference between the main part and substitute lies only in the packaging configuration (tape & reel batch designation), which does not affect electrical performance or mechanical compatibility. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and belong to the same TransZorb® series.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCG60A-M3/9AT and SMCG60A-E3/57T are active production components with identical electrical specifications and mechanical compatibility. Selection between these parts should be based on:

• Inventory availability: SMCG60A-E3/57T currently has 1709 pieces in stock versus 1078 pieces for SMCG60A-M3/9AT
• Packaging batch requirements: Both are supplied in Tape & Reel (TR) configuration with identical DO-215AB package geometry
• Compliance requirements: Both meet ROHS3 compliance and REACH unaffected status, suitable for regulated applications
• Supply chain considerations: Both are manufactured by the same division and maintain identical product status

No electrical re-qualification is required when substituting between these part numbers, as all critical parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can SMCG60A-E3/57T be used as a direct replacement for SMCG60A-M3/9AT in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The difference in part number suffix reflects only the tape & reel batch designation and does not affect performance or compatibility. No circuit modifications or re-testing are required.

Q: Are there any differences in the DO-215AB package between these two parts?

A: No. Both parts use the identical DO-215AB SMC Gull Wing package with the same mechanical dimensions and pin configuration. They are interchangeable at the PCB assembly level.

Q: What is the significance of the different part number suffixes (-M3/9AT versus -E3/57T)?

A: The suffix designates the tape & reel packaging batch from Vishay. This is a manufacturing and supply chain identifier and does not indicate any difference in the component's electrical characteristics, performance ratings, or reliability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMCG60A-M3/9AT and SMCG60A-E3/57T are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. They are suitable for identical applications and regulatory environments.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match exactly: reverse standoff voltage (60V), breakdown voltage (66.7V), clamping voltage (96V), peak pulse current (15.5A), peak pulse power (1500W), package type (DO-215AB), mounting type (surface mount), and channel configuration (unidirectional, 1 channel).
