SA7.0C Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The SA7.0C is a 7V Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient protection applications. This bidirectional Zener diode features a 12.6V maximum clamping voltage and 42.5A peak pulse current capability in a DO-204AC (DO-15) through-hole package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SA7.0C are qualified based on the following electrical and mechanical parameters:

• Reverse standoff voltage within the 7V specification
• Breakdown voltage minimum between 7.37V and 7.79V
• Clamping voltage maximum between 12V and 12.6V
• Peak pulse current capability of 42.5A or greater
• Peak pulse power of 500W or greater
• Through-hole mounting in DO-204AC or DO-15 package
• Operating temperature range of -55°C to 175°C
• Bidirectional Zener diode configuration with single channel

All substitute parts maintain compatibility with the original SA7.0C electrical performance envelope and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

SA7.0CA (onsemi) and SA7.0CA-AP / SA7.0CA-BP (Micro Commercial Co) are direct functional equivalents with active product status. These parts maintain identical electrical specifications within the SA7.0 series and are available in standard through-hole packaging. onsemi's SA7.0CA offers the widest availability and established supply chain presence.

P6KE8V2CA (Taiwan Semiconductor Corporation) is a manufacturer-recommended substitute with enhanced performance characteristics. This part provides higher peak pulse current (50A versus 42.5A) and greater peak pulse power (600W versus 500W), offering additional margin for transient protection applications. The P6KE8V2CA maintains clamping voltage compatibility and is ROHS3 compliant. Operating temperature range is not specified for this part.

All substitute parts are classified as active products with established manufacturing and distribution channels, ensuring long-term availability compared to the obsolete SA7.0C.

Frequently Asked Questions (FAQ)

Q: Can SA7.0CA be used as a direct replacement for SA7.0C?

A: Yes. SA7.0CA maintains identical reverse standoff voltage (7V), equivalent clamping voltage (12V versus 12.6V), and matching peak pulse current (42.5A) and power (500W). Both parts use DO-204AC / DO-15 through-hole packaging and operate across -55°C to 175°C. SA7.0CA is an active product from onsemi.

Q: What is the difference between SA7.0CA-AP and SA7.0CA-BP?

A: Both parts are manufactured by Micro Commercial Co and share identical electrical specifications. The suffix designations (-AP and -BP) indicate different manufacturing or distribution batches. Electrical performance, package type (DO-15), and operating temperature range are equivalent.

Q: Is P6KE8V2CA a suitable substitute?

A: P6KE8V2CA is a manufacturer-recommended substitute with enhanced specifications. It provides higher peak pulse current (50A) and power (600W) while maintaining compatible clamping voltage (12.1V) and reverse standoff voltage (7.02V). This part is suitable for applications requiring additional transient protection margin. Operating temperature range is not specified in available documentation.

Q: Are all substitute parts available in the same package?

A: SA7.0CA is available in DO-204AC and DO-15 packages. SA7.0CA-AP, SA7.0CA-BP, and P6KE8V2CA are available in DO-15 package only. Verify package availability against your specific PCB layout requirements.

Q: What compliance certifications apply to these substitute parts?

A: SA7.0C and P6KE8V2CA are ROHS3 compliant. All parts listed are classified under ECCN EAR99 and HTSUS 8541.10.0080. Moisture sensitivity level is 1 (Unlimited) for SA7.0C and P6KE8V2CA.
