SMBG5.0-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG5.0-E3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This component is designed for general-purpose transient voltage suppression applications with a 5V reverse standoff voltage and 9.6V maximum clamping voltage. The part is currently classified as obsolete, making identification of suitable substitutes essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG5.0-E3/52 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 5V and breakdown voltage minimum of 6.4V
• Package Type: DO-215AA (SMB Gull Wing) surface mount configuration
• Unidirectional Configuration: Single channel Zener TVS diode
• Thermal Range: Operating temperature range of -55°C to 150°C
• Compliance: ROHS3 compliance and MSL 1 rating

The SMBG5.0A-E3/52 meets all substitution criteria. While minor variations exist in clamping voltage (9.2V vs. 9.6V) and peak pulse current (65.2A vs. 62.5A), these remain within the functional tolerance band for the 5V TVS diode category and do not compromise circuit protection performance.

Parameter Comparison

Engineering Selection Recommendations

The SMBG5.0A-E3/52 is the direct substitute for the obsolete SMBG5.0-E3/52. Both components share identical voltage ratings, package configuration, and thermal specifications. The SMBG5.0A-E3/52 carries active product status from the same manufacturer, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The minor parameter variations in clamping voltage and peak pulse current do not affect functional equivalence for general-purpose transient voltage suppression applications.

Frequently Asked Questions (FAQ)

Q: Can the SMBG5.0A-E3/52 be used as a direct replacement for the SMBG5.0-E3/52?

A: Yes. Both components share identical voltage ratings (5V reverse standoff, 6.4V minimum breakdown), package type (DO-215AA SMB), thermal range (-55°C to 150°C), and compliance certifications (ROHS3, MSL 1). The SMBG5.0A-E3/52 is the active production equivalent.

Q: What are the key differences between these two parts?

A: The SMBG5.0A-E3/52 has a slightly lower maximum clamping voltage (9.2V vs. 9.6V) and marginally higher peak pulse current capability (65.2A vs. 62.5A). Both remain within the functional specification band for 5V TVS diodes. The primary difference is product status: SMBG5.0-E3/52 is obsolete, while SMBG5.0A-E3/52 is active.

Q: Are there any package or mounting differences?

A: No. Both parts use the DO-215AA (SMB Gull Wing) surface mount package. PCB footprints and assembly processes are identical.

Q: What compliance certifications apply to both parts?

A: Both the SMBG5.0-E3/52 and SMBG5.0A-E3/52 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.
