SMBG9.0C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG9.0C-E3/52 is a bidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient protection applications. This component features a 9V reverse standoff voltage with a 16.9V maximum clamping voltage and 35.5A peak pulse current capability in a surface-mount DO-215AA (SMB) package.

The SMBG9.0C-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 applications utilizing this TVS diode specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG9.0C-E3/52 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 9V and breakdown voltage minimum of 10V
• Package Type: DO-215AA (SMB Gull Wing) surface-mount configuration
• Electrical Performance: Peak pulse current capability and clamping voltage characteristics
• Thermal Range: Operating temperature range of -55°C to 150°C (TJ)
• Compliance: ROHS3 compliance and MSL rating of 1

The SMBG9.0CA-E3/52 qualifies as a direct substitute based on matching voltage ratings, package configuration, thermal specifications, and regulatory compliance. Both parts belong to the TransZorb® series and maintain identical reverse standoff and breakdown voltage parameters.

Parameter Comparison

Engineering Selection Recommendations

The SMBG9.0CA-E3/52 is the qualified substitute for the obsolete SMBG9.0C-E3/52. Both parts maintain identical voltage ratings, thermal operating range, and regulatory compliance status (ROHS3 compliant, MSL 1). The substitute part is currently in active production status with higher inventory availability.

The SMBG9.0CA-E3/52 demonstrates improved electrical performance characteristics: the clamping voltage is reduced to 15.4V (compared to 16.9V), and peak pulse current is increased to 39A (compared to 35.5A). These parameters remain within the functional requirements for general-purpose transient voltage suppression applications requiring 9V standoff protection.

Selection of the substitute part is supported by identical package configuration, matching thermal specifications, and equivalent regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the SMBG9.0CA-E3/52 be used as a direct replacement for the SMBG9.0C-E3/52?

A: Yes. Both parts share identical reverse standoff voltage (9V), breakdown voltage (10V minimum), package type (DO-215AA SMB), thermal operating range (-55°C to 150°C), and regulatory compliance (ROHS3, MSL 1). The substitute part is currently in active production.

Q: What are the differences between these two parts?

A: The primary differences are product status and electrical performance characteristics. The SMBG9.0CA-E3/52 features a lower maximum clamping voltage (15.4V versus 16.9V) and higher peak pulse current (39A versus 35.5A). Both maintain 600W peak pulse power rating.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical DO-215AA (SMB Gull Wing) surface-mount packaging. The SMBG9.0CA-E3/52 is supplied in Tape & Reel (TR) format, while the original part number does not specify packaging format in the provided data.

Q: What is the significance of the product status difference?

A: The SMBG9.0C-E3/52 is classified as obsolete, indicating discontinued production. The SMBG9.0CA-E3/52 is active production status with significantly higher inventory availability (4098 pieces versus 844 pieces), supporting long-term supply chain continuity.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and carry MSL rating of 1 (unlimited moisture sensitivity level), meeting current regulatory and environmental standards.
