CSRS065V0P Equivalent & Substitute Parts

Part Overview

The CSRS065V0P is a Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose power line protection applications. This steering-type TVS diode features a 5V reverse standoff voltage with a 9V maximum clamping voltage and 6.5A peak pulse current rating in an SOT-23-6 surface mount package.

The CSRS065V0P is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRS065V0P is determined by the following critical parameters:

Primary Compatibility Criteria:

• Reverse standoff voltage: 5V (Max)
• Steering-type TVS diode configuration with 4 unidirectional channels
• Surface mount package: SOT-23-6
• Power line protection capability
• Operating temperature range compatibility

Substitute Parts Identified:

CPDT6-5V0UPC-HF (Comchip Technology): Meets primary compatibility criteria with identical reverse standoff voltage (5V), steering configuration (4 channels), and SOT-23-6 package. This part is active status with enhanced specifications: 12.5V clamping voltage, 10A peak pulse current, and extended operating temperature range (-40°C ~ 125°C). RoHS3 compliant.

D1213A-04TS-7 (Diodes Incorporated): Meets core compatibility criteria with steering configuration (4 channels) and SOT-23-6 package footprint. However, this part features a different reverse standoff voltage (3.3V) and lower peak pulse current (1A at 8/20µs). Automotive-grade with AEC-Q101 qualification and extended operating temperature range (-65°C ~ 150°C). RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

CPDT6-5V0UPC-HF is the primary recommended substitute for the CSRS065V0P. Both parts share identical reverse standoff voltage (5V), steering configuration, and SOT-23-6 package. CPDT6-5V0UPC-HF is active status with RoHS3 compliance, ensuring long-term availability and regulatory alignment. The enhanced specifications (12.5V clamping, 10A peak pulse current, 125W peak power) provide superior performance margins for power line protection applications. Extended operating temperature range (-40°C ~ 125°C) supports broader deployment scenarios.

D1213A-04TS-7 is a secondary substitute option suitable for applications with lower current requirements. This part maintains steering configuration and SOT-23-6 package compatibility but features a reduced reverse standoff voltage (3.3V) and significantly lower peak pulse current (1A). The automotive-grade qualification (AEC-Q101) and extended temperature range (-65°C ~ 150°C) make this part suitable for automotive and high-reliability applications where lower current protection is acceptable. RoHS3 compliance is confirmed.

Selection between these substitutes depends on application-specific current and voltage requirements. Direct replacement with CPDT6-5V0UPC-HF is appropriate for designs requiring equivalent or higher performance specifications. D1213A-04TS-7 requires circuit-level evaluation due to differing electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can CPDT6-5V0UPC-HF directly replace CSRS065V0P without circuit modification?

A: Yes. Both parts share identical reverse standoff voltage (5V), steering configuration (4 channels), and SOT-23-6 package. CPDT6-5V0UPC-HF provides enhanced specifications with higher clamping voltage (12.5V vs. 9V) and peak pulse current (10A vs. 6.5A), making it a direct upgrade-compatible substitute.

Q: What are the key differences between CPDT6-5V0UPC-HF and D1213A-04TS-7?

A: CPDT6-5V0UPC-HF maintains the 5V reverse standoff voltage of the original part with higher current handling (10A). D1213A-04TS-7 features a lower reverse standoff voltage (3.3V) and significantly reduced peak pulse current (1A). Selection depends on circuit voltage and current protection requirements.

Q: Is D1213A-04TS-7 suitable for direct replacement in all applications?

A: No. D1213A-04TS-7 has a different reverse standoff voltage (3.3V vs. 5V) and lower peak pulse current (1A vs. 6.5A). This part is suitable only for applications with lower voltage and current protection requirements. Circuit-level evaluation is required before substitution.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CPDT6-5V0UPC-HF and D1213A-04TS-7 are RoHS3 compliant. Both parts are REACH unaffected with MSL rating of 1 (Unlimited).

Q: What is the package compatibility between these parts?

A: All three parts use SOT-23-6 surface mount packages with identical footprints. PCB layout modifications are not required for substitution.

Q: Which substitute part is recommended for new designs?

A: CPDT6-5V0UPC-HF is recommended for new designs. This part is active status with confirmed long-term availability, RoHS3 compliance, and superior performance specifications compared to the obsolete CSRS065V0P.
