SMBG58CA-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG58CA-E3/52 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 58V reverse standoff voltage class and provides transient protection for general-purpose applications. The part is active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the SMBG58CA-E3/52 is determined by strict equivalence in the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Voltage - Breakdown (Min): 64.4V
• Voltage - Clamping (Max) @ Ipp: 93.6V
• Current - Peak Pulse (10/1000µs): tolerance within ±5% acceptable
• Power - Peak Pulse: 600W minimum
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package Classification: SMB family (DO-214AA, DO-215AA)
• Compliance: RoHS3 Compliant, MSL 1

The SMBJ58CA-TR (STMicroelectronics) meets all substitution criteria with identical voltage specifications and equivalent peak pulse current (6.7A vs. 6.4A). Both parts operate within the same temperature range, share SMB package family compatibility, and maintain full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBG58CA-E3/52 and SMBJ58CA-TR are active production components with identical compliance certifications (RoHS3, REACH Unaffected) and unlimited moisture sensitivity ratings. Selection between these parts is based on:

• Availability and inventory status
• Packaging format preference (Tape & Reel vs. Cut Tape / Digi-Reel®)
• Package variant compatibility (DO-215AA Gull Wing vs. DO-214AA standard SMB)
• Supply chain lead time requirements

Both parts satisfy the electrical requirements for 58V TVS diode applications with equivalent clamping performance and thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can SMBJ58CA-TR directly replace SMBG58CA-E3/52 in existing designs?

A: Yes, provided the PCB layout accommodates the package variant difference. The SMBG58CA-E3/52 uses DO-215AA (SMB Gull Wing), while SMBJ58CA-TR uses DO-214AA (standard SMB). Both are surface mount packages in the SMB family with compatible footprints for most applications. Verify PCB pad geometry before substitution.

Q: What is the significance of the voltage parameters in substitution?

A: The three voltage specifications—Reverse Standoff (58V), Breakdown (64.4V), and Clamping (93.6V)—define the protection threshold and response characteristics. Substitutes must match these values exactly to ensure equivalent transient suppression performance in the protected circuit.

Q: Are there differences in peak pulse current between these parts?

A: The SMBG58CA-E3/52 specifies 6.4A peak pulse current, while SMBJ58CA-TR specifies 6.7A. This 4.7% difference remains within acceptable tolerance for general-purpose TVS applications and does not affect substitution validity.

Q: What packaging considerations apply to these parts?

A: The SMBG58CA-E3/52 is supplied in Tape & Reel (TR) format, while SMBJ58CA-TR is available in Cut Tape (CT) and Digi-Reel® formats. Packaging choice affects handling, storage, and automated assembly compatibility but does not impact electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBG58CA-E3/52 and SMBJ58CA-TR are RoHS3 Compliant, REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity rating. They are equivalent for applications requiring these certifications.
