Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ7.0CE3/TR13 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 7V ± tolerance
• Voltage - Breakdown (Min): 7.78V or higher
• Voltage - Clamping (Max) @ Ipp: 12V to 13.3V range
• Current - Peak Pulse (10/1000µs): 45.1A or higher
• Power - Peak Pulse: 600W minimum

Mechanical Compatibility Criteria:

• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Compliance & Environmental Criteria:

• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

Substitute parts must satisfy all electrical parameters within the specified ranges, maintain identical mechanical packaging, and meet all compliance requirements. Parts with clamping voltages below 12V or peak pulse currents below 45.1A do not qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with full RoHS3 compliance and MSL 1 (Unlimited) rating, meeting the compliance and environmental requirements of the SMBJ7.0CE3/TR13.

SMBJ7.0CA-TP (Micro Commercial Co): This part maintains identical reverse standoff voltage (7V) and breakdown voltage (7.78V) specifications. The clamping voltage is reduced to 12V and peak pulse current is increased to 50A. Operating temperature range extends to 175°C maximum, providing enhanced thermal performance. This substitute is suitable for applications where the lower clamping voltage is acceptable and extended temperature operation is beneficial.

SMBJ7.0CA (MDD): This part provides matching reverse standoff and breakdown voltages with 12V clamping and 50A peak pulse current. Operating temperature range is -50°C to 150°C. This substitute is suitable for general-purpose applications with standard temperature requirements.

SMBJ7.0CA-13-F (Diodes Incorporated): This part matches the reverse standoff voltage (7V) and breakdown voltage (7.78V) with 12V clamping and 50A peak pulse current. Operating temperature range is -55°C to 150°C. This substitute provides compatibility across the specified temperature range.

SMBJ7V0CA (Taiwan Semiconductor Corporation): This part maintains identical electrical specifications with 7V reverse standoff, 7.78V breakdown, 12V clamping, and 50A peak pulse current. Operating temperature range is -55°C to 150°C. This substitute offers the highest inventory availability (27018 Pcs) among all alternatives.

P6SMB8.2CA (Taiwan Semiconductor Corporation): This part operates at 7.02V reverse standoff with 7.79V breakdown voltage and 12.1V clamping. Peak pulse current is increased to 52A. Operating temperature range is -55°C to 150°C. This substitute is suitable when slightly higher voltage ratings and current capacity are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ7.0CA-TP substitute for the SMBJ7.0CE3/TR13 in all applications?

A: The SMBJ7.0CA-TP is electrically compatible with matching reverse standoff and breakdown voltages. The clamping voltage is reduced from 13.3V to 12V, and peak pulse current is increased from 45.1A to 50A. Applications requiring the specific 13.3V clamping characteristic must evaluate whether 12V clamping is acceptable. The extended operating temperature range (-55°C to 175°C) provides additional thermal margin.

Q: What is the difference between the SMBJ7.0CA variants from different manufacturers?

A: The SMBJ7.0CA part number is offered by multiple manufacturers (MDD, Micro Commercial Co, Diodes Incorporated, Taiwan Semiconductor Corporation). All variants maintain the same reverse standoff voltage (7V) and breakdown voltage (7.78V). Differences exist in clamping voltage (12V across all variants), peak pulse current (50A across all variants), and operating temperature ranges. Selection between manufacturers is based on inventory availability, lead time, and specific temperature requirements.

Q: Is the P6SMB8.2CA a direct substitute for the SMBJ7.0CE3/TR13?

A: The P6SMB8.2CA is functionally compatible as a TVS diode in the 7V class with similar electrical performance. The reverse standoff voltage is 7.02V (compared to 7V), breakdown voltage is 7.79V (compared to 7.78V), and clamping voltage is 12.1V (compared to 13.3V). Peak pulse current is increased to 52A. The slightly higher voltage ratings and current capacity make this part suitable for applications where these characteristics are acceptable.

Q: Why does the SMBJ7.0CE3/TR13 have a higher clamping voltage (13.3V) compared to substitute parts (12V)?

A: Clamping voltage variation within the same voltage class is a normal characteristic of TVS diode manufacturing. The SMBJ7.0CE3/TR13 exhibits 13.3V clamping at peak pulse current (45.1A), while substitute parts clamp at 12V at their respective peak pulse currents (50A or 52A). Applications sensitive to the specific clamping voltage must verify that the substitute part's clamping characteristic is acceptable for the circuit protection requirement.

Q: Are all substitute parts available in tape and reel packaging?

A: All substitute parts listed are supplied in tape and reel (TR) format, matching the packaging of the SMBJ7.0CE3/TR13. The DO-214AA (SMB) package is consistent across all parts, ensuring mechanical compatibility with existing PCB designs and automated assembly processes.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080. These certifications match the compliance profile of the SMBJ7.0CE3/TR13, ensuring regulatory compatibility across all substitutes.

Q: Can the SMBJ7V0CA be used as a long-term alternative to the SMBJ7.0CE3/TR13?

A: The SMBJ7V0CA is an active product with the highest inventory availability (27018 Pcs) among all substitutes. It maintains identical reverse standoff voltage (7V), breakdown voltage (7.78V), and peak pulse current (50A) specifications. The clamping voltage is 12V, and operating temperature range is -55°C to 150°C. This part is suitable as a long-term alternative when the lower clamping voltage is acceptable for the application.
