SMBG6.5C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG6.5C-E3/52 is a Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient voltage protection in surface-mount applications. This component features a 6.5V reverse standoff voltage with a 12.3V maximum clamping voltage and 48.8A peak pulse current capability in a DO-215AA (SMB) package.

The SMBG6.5C-E3/52 is classified as obsolete. Identifying suitable substitute components ensures design continuity and maintains supply chain reliability for applications requiring equivalent transient voltage suppression performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBG6.5C-E3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Series: TransZorb®
• Type: Zener, Bidirectional Channels: 1

The SMBG6.5CA-E3/52 qualifies as a direct substitute based on identical reverse standoff voltage, breakdown voltage, package configuration, mounting type, and operating temperature range. Both components are manufactured by Vishay General Semiconductor - Diodes Division within the same TransZorb® series and share the same electrical classification.

Parameter Comparison

Engineering Selection Recommendations

The SMBG6.5CA-E3/52 is the qualified substitute for the obsolete SMBG6.5C-E3/52. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The substitute part maintains identical reverse standoff voltage (6.5V), breakdown voltage (7.22V), operating temperature range (-55°C ~ 150°C), and package configuration (DO-215AA, SMB Gull Wing). The SMBG6.5CA-E3/52 offers improved peak pulse current capability (53.6A versus 48.8A) and a lower maximum clamping voltage (11.2V versus 12.3V), providing enhanced transient suppression performance within the same thermal and mechanical envelope.

The active product status of the SMBG6.5CA-E3/52 ensures long-term availability and supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the SMBG6.5CA-E3/52 directly replace the SMBG6.5C-E3/52 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (6.5V), breakdown voltage (7.22V), operating temperature range, and DO-215AA package configuration. The substitute part is pin-compatible and functionally equivalent for general-purpose transient voltage suppression applications.

Q: What are the key differences between these two parts?

A: The SMBG6.5CA-E3/52 provides higher peak pulse current (53.6A versus 48.8A) and lower maximum clamping voltage (11.2V versus 12.3V). The original part is obsolete; the substitute is active and readily available.

Q: Are there packaging differences between the SMBG6.5C-E3/52 and SMBG6.5CA-E3/52?

A: Both components use the DO-215AA (SMB Gull Wing) surface-mount package. The SMBG6.5CA-E3/52 is supplied in Tape & Reel (TR) format, which is standard for production environments.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SMBG6.5C-E3/52 and SMBG6.5CA-E3/52 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the clamping voltage lower on the substitute part?

A: The SMBG6.5CA-E3/52 achieves lower clamping voltage (11.2V) while maintaining the same reverse standoff voltage (6.5V) through improved device design. This provides superior transient suppression performance without affecting circuit compatibility.
