SMBG5.0A-M3/5B Equivalent & Substitute Parts

Part Overview

The SMBG5.0A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface-mount component is designed for general-purpose transient voltage protection applications. The device features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 65.2A peak pulse current capability in a compact DO-215AA (SMB) package. As an active product with full RoHS3 compliance, substitute parts may be required due to inventory availability, supply chain considerations, or specific packaging preferences while maintaining identical electrical performance.

Substitute Part Grouping Explanation

Substitution of the SMBG5.0A-M3/5B is permissible with parts that maintain identical electrical characteristics across all critical protection parameters. The following criteria define acceptable substitutes:

• Voltage - Reverse Standoff: 5V (exact match)
• Voltage - Breakdown (Min): 6.4V (exact match)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match)
• Current - Peak Pulse (10/1000µs): 65.2A (exact match)
• Power - Peak Pulse: 600W (exact match)
• Package / Case: DO-215AA, SMB Gull Wing (exact match)
• Mounting Type: Surface Mount (exact match)
• Type: Zener, Unidirectional (exact match)

Substitutes must be from the same manufacturer series (TransZorb®) with active product status and full RoHS3 compliance. Variations in operating temperature range and packaging format (Tape & Reel) do not affect functional substitutability for circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBG5.0A-M3/5B and SMBG5.0A-E3/52 are active products with identical electrical specifications and full regulatory compliance (RoHS3, REACH Unaffected). Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (both supplied in Tape & Reel)
• Operating temperature range requirements: The SMBG5.0A-M3/5B supports -65°C to 175°C, while the SMBG5.0A-E3/52 supports -55°C to 150°C. Applications requiring extended low-temperature operation below -55°C or high-temperature operation above 150°C must use the SMBG5.0A-M3/5B.
• Supply chain and cost considerations

Both parts are functionally equivalent for standard general-purpose transient voltage protection circuits operating within the overlapping temperature range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can SMBG5.0A-E3/52 be used as a direct replacement for SMBG5.0A-M3/5B?

A: Yes, for applications operating within the temperature range of -55°C to 150°C. Both parts have identical electrical characteristics (5V standoff, 9.2V clamping, 65.2A peak pulse current) and the same DO-215AA package. If your circuit operates below -55°C or above 150°C, the SMBG5.0A-M3/5B is required due to its extended operating temperature range.

Q: What is the difference between these two part numbers?

A: The primary difference is the operating temperature range. SMBG5.0A-M3/5B operates from -65°C to 175°C, while SMBG5.0A-E3/52 operates from -55°C to 150°C. All electrical protection parameters are identical.

Q: Are both parts available in the same packaging format?

A: Yes, both parts are supplied in Tape & Reel (TR) format and use the same DO-215AA SMB Gull Wing package for surface-mount assembly.

Q: Do these parts have the same compliance certifications?

A: Yes, both parts are RoHS3 compliant, REACH unaffected, and have MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Which part should I specify for a new design?

A: Specify based on your circuit's operating temperature requirements. For standard room-temperature applications, either part is acceptable. For extended temperature range applications, verify that your operating conditions fall within -55°C to 150°C (SMBG5.0A-E3/52) or require the full -65°C to 175°C range (SMBG5.0A-M3/5B).
