Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ6.5CAHM3_A/I is determined by strict equivalence across the following critical 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
• Bidirectional Channels: 1
• Package / Case: DO-214AA, SMB
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Type: Zener
• Series: TransZorb®

The SMBJ6.5CAHM3_B/I qualifies as a direct substitute, maintaining identical electrical performance specifications and package configuration while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ6.5CAHM3_B/I is the manufacturer-recommended substitute for the obsolete SMBJ6.5CAHM3_A/I. Both components maintain identical electrical specifications, thermal operating range, and automotive-grade AEC-Q101 qualification. The substitute part carries Active product status, ensuring ongoing availability and supply chain support.

Both parts comply with ROHS3 and REACH requirements, with EAR99 export classification. The primary distinction is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.5CAHM3_B/I be used as a direct replacement for SMBJ6.5CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 6.5V reverse standoff voltage, 11.2V clamping voltage, 53.6A peak pulse current, 600W peak power, DO-214AA SMB package, and -55°C to 150°C operating temperature range. The substitute carries Active product status, providing supply continuity.

Q: What is the difference between the two part numbers?

A: The SMBJ6.5CAHM3_A/I is Obsolete, while SMBJ6.5CAHM3_B/I is Active. The substitute is supplied in Tape & Reel packaging format. Electrical performance and package dimensions are identical.

Q: Are both parts automotive-qualified?

A: Yes. Both SMBJ6.5CAHM3_A/I and SMBJ6.5CAHM3_B/I carry Automotive grade classification and AEC-Q101 qualification, meeting automotive reliability and quality standards.

Q: What packaging formats are available?

A: The main part (SMBJ6.5CAHM3_A/I) uses standard packaging. The substitute (SMBJ6.5CAHM3_B/I) is supplied in Tape & Reel format, suitable for automated assembly processes.

Q: Are there any environmental compliance differences?

A: No. Both parts are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level (MSL) of 1 (Unlimited).
