SMBG5.0C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG5.0C-E3/52 is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at a 5V reverse standoff voltage with a 9.6V maximum clamping voltage and 62.5A peak pulse current rating. It is designed for general-purpose transient voltage suppression applications in DO-215AA (SMB) packaging.

The SMBG5.0C-E3/52 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS diodes is determined by strict alignment of electrical and mechanical parameters. The following criteria establish whether a part qualifies as a direct substitute for the SMBG5.0C-E3/52:

Critical Matching Parameters:

• Reverse standoff voltage: 5V (Typ)
• Breakdown voltage minimum: 6.4V
• Package type: DO-215AA (SMB Gull Wing)
• Mounting configuration: Surface Mount
• Bidirectional channel count: 1
• Operating temperature range: -55°C to 150°C (TJ)

Allowable Variation Parameters:

• Clamping voltage (Max) @ Ipp: ±0.4V tolerance
• Peak pulse current (10/1000µs): ±2.7A tolerance
• Peak pulse power: Equal or greater capacity

The SMBG5.0CA-E3/52 meets all critical matching parameters and falls within allowable variation ranges for electrical performance metrics, qualifying it as a direct substitute.

Engineering Selection Recommendations

The SMBG5.0CA-E3/52 is the qualified substitute for the obsolete SMBG5.0C-E3/52. Both components are manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series and maintain identical mechanical compatibility and electrical performance within specified tolerances.

Selection Basis:

The SMBG5.0CA-E3/52 demonstrates superior supply chain availability (15,727 units in stock versus 1,046 units for the original part) and maintains active product status, ensuring long-term procurement viability. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The substitute exhibits improved peak pulse current capability (65.2A versus 62.5A) while maintaining equivalent power dissipation capacity (600W) and a lower clamping voltage (9.2V versus 9.6V), providing enhanced transient suppression performance.

The packaging difference (Tape & Reel for the substitute versus unspecified for the original) does not affect functional compatibility and is standard for active production components.

Frequently Asked Questions (FAQ)

Q: Can the SMBG5.0CA-E3/52 be used as a direct replacement for the SMBG5.0C-E3/52 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (5V), breakdown voltage (6.4V minimum), operating temperature range (-55°C to 150°C), and DO-215AA package configuration. The substitute operates within allowable electrical parameter tolerances and maintains full mechanical compatibility.

Q: What is the significance of the clamping voltage difference (9.6V versus 9.2V)?

A: The SMBG5.0CA-E3/52 exhibits a lower maximum clamping voltage by 0.4V, which represents improved transient suppression performance. This variance falls within acceptable engineering tolerances for TVS diode substitution and does not compromise circuit protection.

Q: Why does the substitute have higher peak pulse current (65.2A versus 62.5A)?

A: The increased peak pulse current rating indicates enhanced surge handling capability. This improvement does not create compatibility issues and provides additional design margin for transient event suppression.

Q: Does the Tape & Reel packaging of the substitute affect compatibility?

A: No. Tape & Reel is a standard packaging format for surface mount components and does not affect electrical performance or mechanical fit. The component dimensions and lead configuration remain identical to the original part.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the SMBG5.0C-E3/52 and SMBG5.0CA-E3/52 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the primary reason to transition from the original part to the substitute?

A: The SMBG5.0C-E3/52 is classified as obsolete, making long-term supply procurement uncertain. The SMBG5.0CA-E3/52 maintains active product status with significantly higher inventory availability, ensuring reliable component sourcing for current and future production requirements.
