Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ6.5CA-M3/52 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 53.6A
• Power - Peak Pulse: 600W
• Type: Zener, Bidirectional
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

All identified substitute parts maintain identical electrical specifications across these parameters. Variations in operating temperature range and packaging format (Tape & Reel vs. Cut Tape) do not affect functional equivalence for circuit protection applications. All substitute parts maintain RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical equivalence to the SMBJ6.5CA-M3/52. Selection among these alternatives is based on availability, supply chain considerations, and compliance requirements:

Vishay General Semiconductor - Diodes Division (SMBJ6.5CA-E3/52): Direct manufacturer alternative with identical specifications and operating temperature range. Recommended for applications requiring consistency with the original design source.

Central Semiconductor Corp (1SMB6.5CA TR13 PBFREE): Extended lower operating temperature limit (-65°C) provides additional thermal margin for cold environment applications. ROHS3 compliant with lead-free designation.

EVVO Semi (SMBJ6.5CA): Extended lower operating temperature limit (-65°C) with highest inventory availability. Suitable for high-volume procurement requirements.

Diodes Incorporated (SMBJ6.5CA-13-F): Active product status with SMBJ series designation. Operating temperature range matches original specification.

Micro Commercial Co (SMBJ6.5CA-TP): Extended upper operating temperature limit (-55°C ~ 175°C) for high-temperature applications. Maintains all electrical specifications.

Taiwan Semiconductor Corporation (SMBJ6V5CA): Highest inventory availability with SMBJ series designation. Operating temperature range matches original specification.

All parts carry ROHS3 compliance and MSL 1 rating, confirming suitability for standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SMBJ6.5CA-M3/52?

A: Substitute parts must match the following electrical specifications: 6.5V reverse standoff voltage, 7.22V minimum breakdown voltage, 11.2V maximum clamping voltage, 53.6A peak pulse current, and 600W peak pulse power. The package must be DO-214AA (SMB) surface mount configuration. All listed parts meet these criteria.

Q: Are there differences in operating temperature ranges among the substitutes?

A: Yes. The original SMBJ6.5CA-M3/52 operates from -55°C to 150°C. Some substitutes extend the lower limit to -65°C (Central Semiconductor Corp 1SMB6.5CA TR13 PBFREE and EVVO Semi SMBJ6.5CA), and one extends the upper limit to 175°C (Micro Commercial Co SMBJ6.5CA-TP). These variations do not affect electrical equivalence but may be relevant for specific thermal environments.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts use the DO-214AA (SMB) package with identical pinout and footprint. They are mechanically and electrically interchangeable for surface mount assembly.

Q: Do all substitutes have the same compliance certifications?

A: All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). They carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications as the original part.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape for automated pick-and-place assembly. Cut Tape (CT) and Digi-Reel packaging are supplied in smaller quantities on tape segments. Both formats contain identical components; the difference is in supply format and quantity per reel. Selection depends on production volume and assembly equipment compatibility.

Q: Are there inventory considerations when selecting a substitute?

A: Inventory levels vary significantly among manufacturers. EVVO Semi SMBJ6.5CA and Taiwan Semiconductor Corporation SMBJ6V5CA show substantially higher stock levels (146,145 and 300,300 units respectively) compared to other options. This may influence lead time and cost for high-volume orders.
