CSRS065V0-G Equivalent & Substitute Parts

Part Overview

The CSRS065V0-G is a steering transient voltage suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose power line protection applications. This component features a 5V reverse standoff voltage rating, 4 unidirectional channels in a surface-mount SOT-23-6 package, and 300W peak pulse power handling capability. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRS065V0-G is determined by the following critical parameters:

• Steering TVS Architecture: All substitutes must feature 4-channel steering (rail to rail) topology for equivalent protection across multiple signal lines
• Voltage Rating Compatibility: Reverse standoff voltage must align with 5V nominal operation; acceptable range includes 3.3V to 5V standoff ratings depending on circuit margin requirements
• Package Compatibility: Surface-mount SOT-23-6 or equivalent thin-profile variants (TSOT-23-6, TSOT-26) maintain mechanical and thermal compatibility
• Power Handling: Peak pulse power rating must support the application's transient energy dissipation requirements
• Operating Temperature Range: Minimum -55°C lower bound and 125°C or higher upper bound required for thermal envelope compatibility
• Functional Application: Power line protection capability must be maintained across all substitute candidates

Two active substitute parts meet these criteria and are available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

SRV05-4.TCT (UMW) is the primary substitute candidate. This part maintains identical 5V reverse standoff voltage, 4-channel steering architecture, and SOT-23-6 package footprint. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and AEC-Q101 automotive qualification provide regulatory alignment. The 20V clamping voltage and 3A peak pulse current exceed the original specification, offering enhanced transient suppression margin. Operating temperature range (-55°C ~ 125°C) covers the lower bound requirement, though the 125°C upper limit is 25°C below the original part.

D1213A-04TS-7 (Diodes Incorporated) serves as a secondary alternative for applications with relaxed voltage margin requirements. This part features a lower 3.3V reverse standoff voltage and 10V clamping voltage, suitable for 3.3V signal rail protection. Active product status and ROHS3 compliance are confirmed. The extended operating temperature range (-65°C ~ 150°C) exceeds the original specification. Package variants include TSOT-23-6 thin profile, maintaining mechanical compatibility. AEC-Q101 automotive qualification is documented.

Both substitutes are active production parts with established supply availability, regulatory compliance, and documented electrical performance suitable for power line protection applications.

Frequently Asked Questions (FAQ)

Q: Can the D1213A-04TS-7 replace the CSRS065V0-G in a 5V circuit?

A: The D1213A-04TS-7 features a 3.3V reverse standoff voltage, which is lower than the original 5V rating. This part is suitable for 3.3V signal protection circuits. For 5V applications, the SRV05-4.TCT is the appropriate substitute, maintaining the 5V standoff voltage specification.

Q: What is the difference between SOT-23-6 and TSOT-26 packaging?

A: Both are surface-mount packages with 6 leads suitable for steering TVS diodes. TSOT-26 is a thin-profile variant that maintains the same footprint and pin configuration as SOT-23-6, ensuring PCB layout compatibility. The D1213A-04TS-7 is available in both package designations.

Q: Does the SRV05-4.TCT meet the original 300W power rating?

A: The SRV05-4.TCT is rated for 60W peak pulse power, which is lower than the original 300W specification. This part is suitable for general-purpose and Ethernet/USB protection applications. Applications requiring 300W dissipation capacity require evaluation of alternative high-power TVS solutions.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the D1213A-04TS-7 and SRV05-4.TCT carry ROHS3 compliance certification, meeting environmental and regulatory requirements for electronic component procurement.

Q: What is the temperature operating range difference between substitutes?

A: The CSRS065V0-G operates from -55°C to 150°C. The SRV05-4.TCT operates from -55°C to 125°C, providing 25°C less upper thermal margin. The D1213A-04TS-7 operates from -65°C to 150°C, exceeding the original range at both extremes. Application thermal requirements determine which substitute is appropriate.

Q: Can I use the SRV05-4.TCT for Ethernet and USB applications?

A: Yes. The SRV05-4.TCT is documented for Ethernet and USB protection applications, with 3A peak pulse current and 20V clamping voltage suitable for these signal standards.
