Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG15-E3/52 is determined by the following critical parameters:

• Reverse Standoff Voltage: 15V (Typ)
• Breakdown Voltage (Min): 16.7V
• Package Type: DO-215AA (SMB Gull Wing)
• Mounting Type: Surface Mount
• Unidirectional Configuration: 1 channel
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Series Classification: TransZorb®

Substitute parts must maintain identical values for these parameters to ensure functional and mechanical compatibility within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The SMBG15A-E3/52 is the direct substitute for the obsolete SMBG15-E3/52. Both components share identical reverse standoff voltage (15V), breakdown voltage (16.7V minimum), package configuration (DO-215AA), and operating temperature range (-55°C to 150°C).

The SMBG15A-E3/52 is currently in active production status with substantial inventory availability (4503 pcs), whereas the SMBG15-E3/52 is obsolete. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

The SMBG15A-E3/52 is supplied in Tape & Reel (TR) packaging, supporting automated assembly processes. Selection of the active substitute part ensures long-term supply chain reliability and eliminates obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Can the SMBG15A-E3/52 be used as a direct replacement for the SMBG15-E3/52?

A: Yes. Both parts share identical reverse standoff voltage (15V), breakdown voltage (16.7V minimum), package type (DO-215AA), and operating temperature range. The SMBG15A-E3/52 is the active equivalent part.
