Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ7.0CA-M3/9AT are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Breakdown (Min): 7.78V minimum
• Voltage - Clamping (Max) @ Ipp: 12V
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Allowable Variation Parameters:

• Current - Peak Pulse (10/1000µs): 125A or higher
• Power - Peak Pulse: 1500W or higher
• Operating Temperature Range: -55°C minimum to 150°C or higher
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1

Substitute parts maintain identical voltage specifications and package form factor while permitting equal or superior current handling and power dissipation ratings. All substitutes comply with ROHS3 and maintain MSL 1 classification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, qualifying them for direct substitution in applications requiring the SMCJ7.0CA-M3/9AT electrical and mechanical specifications.

Vishay SMCJ7.0CA-E3/57T: Identical electrical performance and temperature range to the main part. Packaging designation differs (E3/57T vs. M3/9AT), reflecting alternative tape and reel configurations. Inventory availability is higher at 1750 pieces.

Taiwan Semiconductor SMCJ7.0CA: Matches all critical voltage parameters with marginally higher peak pulse current (131A vs. 125A). Packaging designation omitted in supplier data. Highest inventory availability at 84400 pieces.

Micro Commercial Co SMCJ7.0CA-TP: Meets all electrical requirements with extended operating temperature range to 175°C. Voltage breakdown specification is 7.8V, within acceptable tolerance. Tape and reel packaging confirmed.

Alpha & Omega Semiconductor SMDJ7.0CA: Exceeds electrical performance with doubled peak pulse current (250A) and doubled power dissipation (3000W). Maintains identical voltage clamping and standoff specifications. Moisture sensitivity level not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can SMCJ7.0CA-E3/57T replace SMCJ7.0CA-M3/9AT directly?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications. The suffix difference (E3/57T vs. M3/9AT) indicates alternative tape and reel packaging configurations. Electrical performance and mechanical compatibility are equivalent.

Q: What is the difference between SMCJ7.0CA and SMDJ7.0CA?

A: Both maintain identical voltage specifications (7V standoff, 12V clamping). The SMDJ7.0CA provides superior current handling (250A vs. 125A) and power dissipation (3000W vs. 1500W). Selection depends on application transient energy requirements. Both use DO-214AB surface mount packaging.

Q: Is the Micro Commercial Co SMCJ7.0CA-TP suitable for high-temperature applications?

A: The SMCJ7.0CA-TP operates to 175°C junction temperature, exceeding the main part specification of 150°C. This extended range qualifies it for elevated ambient or self-heating conditions where the main part may reach thermal limits.

Q: Can I use Taiwan Semiconductor SMCJ7.0CA in place of Vishay SMCJ7.0CA-M3/9AT?

A: Yes. The Taiwan Semiconductor part meets all critical electrical parameters with marginally higher peak pulse current (131A). Voltage specifications are identical. Both use DO-214AB surface mount packaging. Substitution is electrically valid.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 classification indicates the component has unlimited shelf life without moisture bake requirements prior to soldering. This applies to the main part and all Vishay and Micro Commercial Co substitutes. The Alpha & Omega SMDJ7.0CA does not specify MSL in available documentation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the main part specification. This ensures compliance with European Union Restriction of Hazardous Substances regulations.
