Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBG14-E3/52 is determined by strict equivalence across the following critical parameters:

• Reverse Standoff Voltage: 14V (nominal)
• Breakdown Voltage (Min): 15.6V
• Package Type: DO-215AA (SMB Gull Wing)
• Mounting Configuration: Surface Mount
• Unidirectional Channel Count: 1
• Series Classification: TransZorb®
• Compliance Standards: ROHS3, REACH Unaffected

The SMBG14A-E3/52 meets all substitution criteria as a direct equivalent within the same product family, with variations only in clamping voltage and peak pulse current specifications that remain within acceptable operational parameters for the same application class.

Parameter Comparison

Engineering Selection Recommendations

The SMBG14A-E3/52 is the direct substitute for the obsolete SMBG14-E3/52. Both components share identical core electrical specifications (14V reverse standoff, 15.6V minimum breakdown voltage) and mechanical compatibility (DO-215AA package, surface mount configuration). The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain equivalent compliance certifications: ROHS3 compliance and REACH unaffected status. The SMBG14A-E3/52 is available in Tape & Reel packaging, supporting automated assembly processes. The minor variations in clamping voltage (25.8V vs. 23.2V) and peak pulse current (23.3A vs. 25.9A) do not affect functional equivalence for general-purpose transient voltage suppression applications within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can SMBG14A-E3/52 be used as a direct replacement for SMBG14-E3/52?

A: Yes. Both components share identical reverse standoff voltage (14V), breakdown voltage (15.6V minimum), package type (DO-215AA), and mounting configuration (surface mount). The substitute part is functionally equivalent for general-purpose TVS applications.

Q: What is the difference between the clamping voltages of these two parts?

A: The SMBG14-E3/52 specifies a maximum clamping voltage of 25.8V at peak pulse current, while the SMBG14A-E3/52 specifies 23.2V. Both values remain within acceptable operational parameters for the same application class and do not affect substitution eligibility.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-215AA (SMB Gull Wing) package for surface mount applications. The SMBG14A-E3/52 is supplied in Tape & Reel format, which is standard for automated assembly. The SMBG14-E3/52 packaging format was not specified in the available data.

Q: What is the product status difference, and does it affect substitution?

A: The SMBG14-E3/52 is listed as obsolete, while the SMBG14A-E3/52 is in active production. This makes the substitute part the recommended choice for new designs and ongoing procurement to ensure supply chain continuity.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SMBG14-E3/52 and SMBG14A-E3/52 are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels (MSL 1 - Unlimited).
