Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG26C-E3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 26V
• Voltage - Breakdown (Min): 28.9V
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

The SMBG26CA-E3/52 qualifies as a direct substitute based on matching reverse standoff voltage, breakdown voltage, package configuration, and mounting type. Both components share identical electrical specifications for standoff and breakdown voltages, ensuring functional compatibility in the same circuit application. The difference in clamping voltage and peak pulse current represents a performance variation within the same product family and does not preclude substitution where the application tolerates these parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The SMBG26CA-E3/52 is the primary substitute for the obsolete SMBG26C-E3/52. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical reverse standoff and breakdown voltage specifications (26V and 28.9V respectively). The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts meet ROHS3 compliance and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), confirming equivalent environmental qualification. The substitute component demonstrates improved peak pulse current capability (14.3A versus 12.9A) and lower clamping voltage (42.1V versus 46.6V), representing a performance enhancement within the same electrical class.

Packaging and mounting configurations are identical (DO-215AA, SMB Gull Wing, surface mount), eliminating any PCB layout or assembly process modifications. Operating temperature ranges are matched across both components (-55°C to 150°C TJ).

Frequently Asked Questions (FAQ)

Q: Can SMBG26CA-E3/52 be used as a direct replacement for SMBG26C-E3/52?

A: Yes. Both components share identical reverse standoff voltage (26V), breakdown voltage (28.9V), package configuration (DO-215AA, SMB Gull Wing), and mounting type (surface mount). These parameters define functional compatibility in TVS diode applications.

Q: What are the differences between these two parts?

A: The primary differences are product status (obsolete versus active) and performance characteristics. The substitute part offers higher peak pulse current (14.3A versus 12.9A) and lower clamping voltage (42.1V versus 46.6V). Both maintain 600W peak pulse power rating.

Q: Are there packaging differences between SMBG26C-E3/52 and SMBG26CA-E3/52?

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

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental and regulatory qualification.

Q: Why is the original part listed as obsolete?

A: The SMBG26C-E3/52 is no longer in active production. The SMBG26CA-E3/52 represents the current active equivalent from the same manufacturer and product series.
