SMCG7.0CA-M3/9AT Equivalent & Substitute Parts

Part Overview

The SMCG7.0CA-M3/9AT is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component is designed for general-purpose transient voltage protection applications, featuring a 7V reverse standoff voltage and 12V maximum clamping voltage. The part is currently in active production status with 929 units available in inventory. Alternative equivalent parts may be required due to supply chain considerations, inventory availability, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMCG7.0CA-M3/9AT is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 125A
• Power - Peak Pulse: 1500W
• Package / Case: DO-215AB, SMC Gull Wing
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

The SMCG7.0CA-HRA manufactured by Littelfuse Inc. meets all critical electrical and mechanical parameters required for direct substitution. Both parts share identical voltage ratings, peak pulse current specifications, power dissipation capability, and physical packaging. The substitute part maintains the same functional performance envelope within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCG7.0CA-M3/9AT and SMCG7.0CA-HRA are active production components with full ROHS3 compliance and identical moisture sensitivity ratings. The electrical performance characteristics are equivalent across all critical transient voltage suppression parameters. The Littelfuse SMCG7.0CA-HRA provides an extended lower operating temperature range (-65°C versus -55°C), which may offer additional margin in applications requiring operation at lower ambient temperatures. Both parts are suitable for direct substitution in general-purpose transient voltage protection circuits where the DO-215AB package and specified voltage/current ratings are required.

Frequently Asked Questions (FAQ)

Q: Can the SMCG7.0CA-HRA be used as a direct replacement for the SMCG7.0CA-M3/9AT?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical voltage ratings (7V reverse standoff, 12V clamping), peak pulse current (125A), power dissipation (1500W), and physical packaging (DO-215AB, SMC Gull Wing surface mount). Both are ROHS3 compliant with MSL 1 rating.

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

A: Substitution is determined by matching: reverse standoff voltage (7V), breakdown voltage (7.78V minimum), clamping voltage (12V maximum), peak pulse current (125A at 10/1000µs), power dissipation (1500W), package type (DO-215AB), mounting configuration (surface mount), and channel configuration (1 bidirectional channel).

Q: Are there any temperature range differences between these parts?

A: The Littelfuse SMCG7.0CA-HRA operates from -65°C to 150°C, while the Vishay SMCG7.0CA-M3/9AT operates from -55°C to 150°C. The Littelfuse part extends the lower temperature limit by 10°C.

Q: Do both parts have the same packaging and handling requirements?

A: Yes. Both parts use DO-215AB surface mount packaging with MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.

Q: Are both parts currently available for production use?

A: Yes. Both the SMCG7.0CA-M3/9AT and SMCG7.0CA-HRA are in active production status with current inventory availability.
