Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB8.2CA are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 7V nominal (tolerance range 6.93V to 7.07V acceptable)
• Voltage - Clamping (Max) @ Ipp: 12V nominal (tolerance range 11.88V to 12.12V acceptable)
• Current - Peak Pulse (10/1000µs): 50A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB equivalent
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain these core electrical specifications within standard engineering tolerances and are packaged in compatible surface-mount configurations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The SMBJ7.0CA-TP variant from Micro Commercial Co offers an extended upper operating temperature limit of 175°C compared to the standard 150°C, providing additional thermal margin in high-temperature applications. The SMBJ7V0CA from Taiwan Semiconductor Corporation maintains the full -55°C to 150°C operating range and offers the highest inventory availability at 27,018 pieces. Selection between substitutes should be based on thermal requirements, lead time, and inventory availability, as all parts meet the core electrical and mechanical specifications for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can SMBJ7.0CA parts be used as direct replacements for P6SMB8.2CA?

A: Yes. The SMBJ7.0CA variants (from MDD, Micro Commercial Co, and Taiwan Semiconductor Corporation) are direct electrical and mechanical equivalents. All maintain the same 7V reverse standoff voltage, 12V clamping voltage, 50A peak pulse current, and DO-214AA/SMB package configuration.

Q: What is the difference between the three SMBJ7.0CA substitute options?

A: The primary differences are manufacturer, operating temperature range, and inventory availability. SMBJ7.0CA-TP supports -55°C to 175°C (extended upper limit), while MDD and Taiwan Semiconductor variants support -55°C to 150°C or -50°C to 150°C respectively. All three maintain identical electrical specifications.

Q: Are there any package compatibility concerns when substituting?

A: No. All substitute parts use the DO-214AA (SMB) surface-mount package, which is mechanically and electrically compatible with the original P6SMB8.2CA footprint.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original P6SMB8.2CA.

Q: What voltage tolerance should be considered when selecting a substitute?

A: The reverse standoff voltage specification of 7V (substitute parts) versus 7.02V (original) represents a 0.3% variance, which is within standard engineering tolerances for TVS diode applications. Both meet the same functional protection requirements.
