Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG6.5A-E3/5B is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): minimum 53.6A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package Category: SMB (DO-215AA or DO-214AA)
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SMBJ6.5A-TR from STMicroelectronics meets all substitution criteria. Both devices share identical voltage ratings, thermal operating range, and compliance certifications. The SMBJ6.5A-TR provides equivalent or superior peak pulse current capability (56A vs. 53.6A) and maintains the same 600W peak pulse power rating. Package compatibility is confirmed through SMB form factor equivalence (DO-214AA vs. DO-215AA).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ6.5A-TR is qualified as a direct substitute for the SMBG6.5A-E3/5B based on electrical parameter equivalence and regulatory compliance alignment. Both devices maintain ROHS3 compliance and MSL Level 1 classification, ensuring compatibility with standard manufacturing and storage protocols. The SMBJ6.5A-TR demonstrates superior peak pulse current capability (56A vs. 53.6A), providing additional margin in transient suppression applications. Both devices are manufactured by established semiconductor suppliers with active product status, supporting long-term supply chain reliability. Selection between these parts should be based on procurement availability, lead time requirements, and cost considerations, as electrical performance and compliance certifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ6.5A-TR replace the SMBG6.5A-E3/5B in existing designs?

A: Yes. The SMBJ6.5A-TR is electrically equivalent across all critical parameters: reverse standoff voltage (6.5V), clamping voltage (11.2V), and thermal operating range (-55°C to 150°C). Both devices are ROHS3 compliant with MSL Level 1 classification. The SMB package form factor is compatible between DO-215AA and DO-214AA variants.

Q: What is the difference in peak pulse current between these parts?

A: The SMBG6.5A-E3/5B is rated at 53.6A peak pulse current, while the SMBJ6.5A-TR is rated at 56A. The SMBJ6.5A-TR provides 2.4A additional current capacity, which represents improved performance margin in transient suppression applications.

Q: Are there packaging differences between these devices?

A: Both devices use the SMB surface mount package form factor. The SMBG6.5A-E3/5B uses DO-215AA (Gull Wing), while the SMBJ6.5A-TR uses DO-214AA. These packages are mechanically and electrically compatible for standard PCB assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG6.5A-E3/5B and SMBJ6.5A-TR are ROHS3 compliant and REACH unaffected. Both carry MSL Level 1 (Unlimited) moisture sensitivity classification and share identical ECCN (EAR99) and HTSUS (8541.10.0080) codes.

Q: What applications are these parts suitable for?

A: Both devices are classified for general-purpose transient voltage suppression. They are not rated for power line protection applications. Selection should be based on specific circuit protection requirements within the defined voltage and current parameters.
