SA64C-E3/73 Equivalent & Substitute Parts

Part Overview

The SA64C-E3/73 is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This component is designed for general-purpose transient voltage suppression applications with a 64V reverse standoff voltage and 114V maximum clamping voltage. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SA64C-E3/73 is determined by the following critical parameters that must remain consistent:

• Voltage - Reverse Standoff: 64V (primary voltage rating)
• Voltage - Breakdown (Min): 71.1V (triggering threshold)
• Package / Case: DO-204AC, DO-15, Axial (physical compatibility)
• Mounting Type: Through Hole (assembly compatibility)
• Type: Zener (functional classification)
• Bidirectional Channels: 1 (circuit topology)
• Operating Temperature Range: -55°C ~ 175°C (environmental compatibility)

Substitute parts may vary in clamping voltage (within acceptable limits for the application) and peak pulse current, provided the reverse standoff voltage and breakdown voltage remain unchanged. All substitute parts must maintain the same package and mounting specifications to ensure direct replacement capability.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (SA64CA-E3/73, SA64CA, and SA64CA-TP) meet the core electrical and mechanical requirements for direct replacement of the SA64C-E3/73. The primary differences are manufacturer, product status, and packaging format.

SA64CA-E3/73 is manufactured by Vishay General Semiconductor - Diodes Division, the original manufacturer of the SA64C-E3/73. This part maintains active product status and ROHS3 compliance, making it the preferred direct equivalent.

SA64CA, manufactured by Taiwan Semiconductor Corporation, is also active and ROHS3 compliant. This part offers equivalent electrical performance with slightly higher peak pulse current (5A vs. 4.4A).

SA64CA-TP, manufactured by Micro Commercial Co, is supplied in bulk packaging and maintains active status. REACH compliance is confirmed, though RoHS status is not specified in the available data.

All substitute parts feature lower clamping voltage (103V vs. 114V), which represents improved performance characteristics for transient suppression while maintaining the same reverse standoff and breakdown voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can SA64CA-E3/73 be used as a direct replacement for SA64C-E3/73?

A: Yes. Both parts share identical reverse standoff voltage (64V), breakdown voltage (71.1V), operating temperature range (-55°C ~ 175°C), package type (DO-204AC, DO-15, Axial), and mounting configuration (Through Hole). The SA64CA-E3/73 is manufactured by the same company and maintains active product status.

Q: What is the difference between SA64CA-E3/73 and SA64CA?

A: Both parts are electrically equivalent with identical voltage ratings and operating temperature ranges. The primary difference is the manufacturer: SA64CA-E3/73 is from Vishay General Semiconductor - Diodes Division, while SA64CA is from Taiwan Semiconductor Corporation. Both maintain active status and ROHS3 compliance.

Q: Why do substitute parts have lower clamping voltage (103V vs. 114V)?

A: The clamping voltage specification represents the maximum voltage at peak pulse current. Lower clamping voltage indicates improved transient suppression performance. All substitute parts maintain the same reverse standoff voltage (64V) and breakdown voltage (71.1V), ensuring proper circuit protection at the intended voltage threshold.

Q: Are there packaging differences between the substitute parts?

A: SA64CA-E3/73 and SA64CA are supplied in standard packaging formats. SA64CA-TP is supplied in bulk packaging. All three parts use the same DO-204AC (DO-15) axial package for through-hole mounting, ensuring physical compatibility.

Q: Do all substitute parts meet compliance requirements?

A: SA64CA-E3/73 and SA64CA are ROHS3 compliant. All substitute parts are REACH unaffected. RoHS status for SA64CA-TP is not specified in available documentation. Verify compliance requirements for your specific application before final selection.
