SMBJ6.5CA Equivalent & Substitute Parts

Part Overview

The SMBJ6.5CA is an active Transient Voltage Suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation. This surface-mount component operates as a bidirectional Zener diode in the DO-214AA (SMB) package, designed for general-purpose transient voltage suppression applications. The device provides 6.5V reverse standoff voltage with 11.2V maximum clamping voltage and 56A peak pulse current capability. Substitute parts are identified to provide equivalent electrical performance and mechanical compatibility for applications requiring alternative sourcing or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ6.5CA are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Voltage - Breakdown (Min): 7.22V
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• Type: Zener
• Bidirectional Channels: 1

Allowable Variation:

• Current - Peak Pulse (10/1000µs): Substitute parts must maintain minimum 53.6A capability to ensure adequate transient suppression performance within the specified clamping voltage envelope.

The P6SMBJ6.5CA_R1_00001 manufactured by Panjit International Inc. meets all critical electrical parameters and mechanical compatibility requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ6.5CA and P6SMBJ6.5CA_R1_00001 are active products with identical regulatory compliance status. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic component manufacturing and distribution.

The P6SMBJ6.5CA_R1_00001 provides equivalent electrical performance within the specified operating parameters. The peak pulse current specification of 53.6A remains within acceptable tolerance for the 11.2V clamping voltage envelope and 600W peak pulse power rating. Both devices operate across the full temperature range of -55°C to 150°C (TJ) and are packaged identically in DO-214AA (SMB) surface-mount format.

Selection between these parts is determined by availability, supply chain requirements, and packaging format preference (bulk versus tape & reel).

Frequently Asked Questions (FAQ)

Q: Can the P6SMBJ6.5CA_R1_00001 be used as a direct replacement for the SMBJ6.5CA?

A: Yes. Both components share identical voltage specifications (6.5V reverse standoff, 7.22V breakdown minimum, 11.2V clamping maximum), identical power rating (600W peak pulse), identical operating temperature range (-55°C to 150°C), and identical package format (DO-214AA, SMB). The peak pulse current difference (53.6A versus 56A) remains within the performance envelope for the specified clamping voltage.

Q: What is the primary difference between these two parts?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Panjit International Inc.), peak pulse current specification (56A versus 53.6A), and packaging format (standard packaging versus tape & reel). All critical electrical parameters and mechanical compatibility remain identical.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both parts are classified as general-purpose TVS diodes with identical voltage and power specifications. They are suitable for identical transient voltage suppression applications requiring 6.5V standoff voltage and 11.2V clamping voltage performance.

Q: What packaging formats are available?

A: The SMBJ6.5CA is supplied in standard packaging. The P6SMBJ6.5CA_R1_00001 is supplied in tape & reel (TR) format, which is standard for high-volume surface-mount assembly operations.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the SMBJ6.5CA and P6SMBJ6.5CA_R1_00001 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Is the 2.4A difference in peak pulse current specification significant?

A: The 2.4A difference (56A versus 53.6A) represents approximately 4.3% variation. Both specifications maintain the 600W peak pulse power rating and 11.2V maximum clamping voltage. This variation is within acceptable tolerance for general-purpose transient suppression applications.
