Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBG24C-E3/5B is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Series: TransZorb®

The SMBG24CA-E3/5B qualifies as a direct substitute based on identical reverse standoff voltage, breakdown voltage, package configuration, and operating temperature range. Both components share the same base product number (SMBG24) and are manufactured by the same supplier, ensuring mechanical and electrical compatibility within the specified parameter tolerances.

Parameter Comparison

Engineering Selection Recommendations

The SMBG24CA-E3/5B is the qualified substitute for the obsolete SMBG24C-E3/5B. Both components maintain identical reverse standoff voltage (24V), breakdown voltage (26.7V), and package configuration (DO-215AA, SMB Gull Wing), ensuring direct mechanical and electrical compatibility.

The substitute component offers improved current handling capability (15.4A versus 14A peak pulse current) and a lower clamping voltage (38.9V versus 43V), both of which represent enhanced performance characteristics within the same thermal and compliance framework. Both parts are ROHS3 compliant with MSL 1 rating and identical operating temperature ranges (-55°C ~ 150°C).

The SMBG24CA-E3/5B carries active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete main part number.

Frequently Asked Questions (FAQ)

Q: Can the SMBG24CA-E3/5B be used as a direct replacement for the SMBG24C-E3/5B?

A: Yes. Both components share identical reverse standoff voltage (24V), breakdown voltage (26.7V), package configuration (DO-215AA, SMB Gull Wing), and operating temperature range (-55°C ~ 150°C). The substitute meets all mechanical and electrical compatibility requirements for direct substitution.

Q: What are the differences between these two part numbers?

A: The primary differences are product status and performance characteristics. The SMBG24CA-E3/5B is active production, while the SMBG24C-E3/5B is obsolete. The substitute offers higher peak pulse current (15.4A versus 14A) and lower clamping voltage (38.9V versus 43V), both representing performance improvements within the same electrical class.

Q: Are there packaging differences between these parts?

A: No. Both components use identical DO-215AA (SMB Gull Wing) surface-mount packaging. No PCB layout or assembly process modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG24C-E3/5B and SMBG24CA-E3/5B are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent.

Q: Which part should be specified for new designs?

A: The SMBG24CA-E3/5B should be specified for new designs due to its active product status and improved performance characteristics. The SMBG24C-E3/5B is obsolete and should only be used for legacy system support or repair applications.
