Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBG10-E3/5B is determined by the following critical parameters:

• Reverse Standoff Voltage: 10V nominal
• Breakdown Voltage (Min): 11.1V
• Package Type: DO-215AA (SMB Gull Wing) surface mount
• Unidirectional Configuration: Single channel
• Temperature Range: -55°C ~ 150°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The SMBG10A-E3/5B qualifies as a direct substitute based on matching reverse standoff voltage, breakdown voltage, package configuration, and operating temperature range. Both components share identical base product designation (SMBG10) and are manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

The SMBG10A-E3/5B is the qualified substitute for the obsolete SMBG10-E3/5B. Selection is based on:

• Electrical Compatibility: Both components maintain identical reverse standoff voltage (10V) and breakdown voltage (11.1V), ensuring functional equivalence in circuit protection applications.
• Package Compatibility: Both use DO-215AA (SMB Gull Wing) surface mount packaging, permitting direct PCB layout substitution without redesign.
• Compliance Alignment: Both components meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.
• Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity.
• Thermal Performance: Identical operating temperature range (-55°C ~ 150°C) maintains thermal design margins.

The SMBG10A-E3/5B offers improved peak pulse current capability (35.3A versus 31.9A) and lower clamping voltage (17V versus 18.8V), providing enhanced transient suppression performance within the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can SMBG10A-E3/5B be used as a direct replacement for SMBG10-E3/5B?

A: Yes. Both components share identical reverse standoff voltage, breakdown voltage, package type, and operating temperature range. The substitute part is electrically and mechanically compatible for direct substitution.

Q: What is the difference in clamping voltage between these parts?

A: The SMBG10-E3/5B has a maximum clamping voltage of 18.8V, while the SMBG10A-E3/5B clamps at 17V. The lower clamping voltage of the substitute provides improved transient suppression performance.

Q: Are both parts available in the same packaging?

A: Yes. Both components use DO-215AA (SMB Gull Wing) surface mount packaging. The SMBG10A-E3/5B is supplied in Tape & Reel (TR) format, which is standard for production assembly.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Why is the original part listed as obsolete?

A: The SMBG10-E3/5B is obsolete, but the SMBG10A-E3/5B remains in active production as the current equivalent offering from Vishay. This substitution ensures continued design support and component availability.

Q: Are there any compliance differences between the parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.
