Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBG5.0A-E3/5B are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Current - Peak Pulse (10/1000µs): 65.2A minimum
• Power - Peak Pulse: 600W (exact match required)
• Operating Temperature Range: -55°C to 150°C (exact match required)
• Unidirectional Channels: 1 (exact match required)
• Type: Zener (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited)

Substitutes are grouped into two categories: direct manufacturer equivalents from Vishay and manufacturer-recommended alternatives from other qualified suppliers that meet all electrical specifications and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the electrical and mechanical requirements for direct substitution in applications requiring 5V TVS diode protection with 9.2V clamping voltage and 600W peak pulse power handling.

SMBG5.0A-E3/52 is a direct equivalent from the same manufacturer (Vishay) with identical electrical specifications and package designation (DO-215AA, SMB Gull Wing). This part is the preferred choice when maintaining exact component consistency within a design or supply chain.

SMBJ5.0A-TR from STMicroelectronics is a manufacturer-recommended alternative that meets all critical electrical parameters. The peak pulse current specification is 68A, which exceeds the 65.2A requirement. The package designation differs (DO-214AA, SMB versus DO-215AA, SMB Gull Wing), though both are surface mount SMB packages. This part is suitable for applications where cross-manufacturer sourcing is acceptable and PCB layout accommodates the package variant.

All three parts are actively manufactured, RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings, ensuring compliance with current regulatory requirements and manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can SMBG5.0A-E3/52 be used as a direct replacement for SMBG5.0A-E3/5B?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications, including 5V reverse standoff voltage, 9.2V clamping voltage, 65.2A peak pulse current, and 600W peak pulse power. The package designation (DO-215AA, SMB Gull Wing) is identical, making this a direct substitution with no design modifications required.

Q: What is the difference between SMBG5.0A-E3/5B and SMBJ5.0A-TR?

A: The primary differences are manufacturer (Vishay versus STMicroelectronics) and package designation (DO-215AA, SMB Gull Wing versus DO-214AA, SMB). Electrically, both meet the 5V standoff, 9.2V clamping, and 600W power specifications. The SMBJ5.0A-TR has a peak pulse current rating of 68A, which exceeds the 65.2A specification. Both packages are surface mount SMB variants and may require PCB layout verification for compatibility.

Q: Are all three parts RoHS3 and REACH compliant?

A: Yes. SMBG5.0A-E3/5B, SMBG5.0A-E3/52, and SMBJ5.0A-TR are all RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: All three parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can SMBJ5.0A-TR be used in place of SMBG5.0A-E3/5B without PCB modifications?

A: The electrical specifications are compatible. However, the package designation differs (DO-214AA, SMB versus DO-215AA, SMB Gull Wing). PCB layout and footprint compatibility must be verified before substitution. Both are surface mount SMB packages, but physical dimensions and lead configurations may differ.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate across the same temperature range: -55°C to 150°C (junction temperature, TJ).
