SA60CA Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts
Part Overview
The SA60CA is a 60V Zener transient voltage suppressor diode in DO-15 axial package, manufactured by onsemi. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The SA60CA provides transient voltage suppression for general-purpose applications with a 96.8V maximum clamping voltage and 5.2A peak pulse current rating. Substitute parts maintain identical electrical specifications while offering active product status from alternative manufacturers.

Substitute Part Grouping Explanation
Substitute parts for the SA60CA are classified into two categories based on electrical and mechanical compatibility:
Direct Equivalents maintain identical electrical specifications (60V standoff, 96.8V clamping, 5.2A peak pulse current) and package format (DO-15/DO-204AC axial through-hole). These parts are interchangeable without circuit modification:
- SA60CA (Taiwan Semiconductor Corporation)
- SA60CA-E3/54 (Vishay General Semiconductor)
- SA60CAHE3/54 (Vishay General Semiconductor - Automotive Grade)
Similar Equivalents maintain the same electrical specifications but originate from alternative manufacturers with different part numbering schemes. These include both SA60CA variants and P5KE60CA variants from Micro Commercial Co, all rated for 60V standoff and 96.8V clamping with 5.2A peak pulse current in DO-15 package format.
Substitution is determined by the following critical parameters: Voltage - Reverse Standoff (60V), Voltage - Clamping (96.8V), Current - Peak Pulse (5.2A minimum), Power - Peak Pulse (500W), Package Type (DO-15/DO-204AC axial), and Mounting Type (Through Hole).

Engineering Selection Recommendations
For Standard Applications: Select SA60CA-E3/54 (Vishay) or SA60CA (Taiwan Semiconductor Corporation) as primary substitutes. Both are active products with ROHS3 compliance and established supply chains. The Vishay part offers the TransZorb® series designation with proven reliability in general-purpose transient suppression.
For Automotive Applications: SA60CAHE3/54 (Vishay) is the qualified choice, featuring AEC-Q101 automotive qualification and -55°C to 175°C operating temperature range. This part maintains identical electrical specifications while meeting automotive-grade reliability requirements.
For Extended Temperature Range: P5KE60CA variants (Micro Commercial Co) support -65°C to 175°C operating temperature, providing wider low-temperature performance. These parts are available in multiple packaging options (AP, BP, TP designations) and maintain active product status.
For Cost-Optimized Procurement: SA60CA-AP, SA60CA-BP, or SA60CA-TP (Micro Commercial Co) provide active alternatives with slightly elevated peak pulse current (5.3A vs. 5.2A), remaining within the 500W power dissipation envelope. These parts are suitable for general-purpose applications where the additional current margin is acceptable.
All substitute parts maintain the critical electrical parameters: 60V reverse standoff voltage, 96.8V maximum clamping voltage, and 500W peak pulse power rating. Package compatibility is confirmed across all options in DO-15/DO-204AC axial through-hole format.
Frequently Asked Questions (FAQ)
Q: Can I directly replace the obsolete onsemi SA60CA with any of the listed substitutes?
A: Yes. All listed substitute parts maintain identical reverse standoff voltage (60V), clamping voltage (96.8V), and power dissipation (500W). Direct pin-for-pin replacement is possible in DO-15 axial package format without circuit modification.
Q: What is the difference between SA60CA and P5KE60CA variants?
A: Both maintain identical electrical specifications (60V standoff, 96.8V clamping, 5.2A peak pulse). The primary difference is manufacturer and part numbering scheme. SA60CA variants are sourced from Taiwan Semiconductor Corporation, Vishay, or Micro Commercial Co. P5KE60CA variants are exclusively from Micro Commercial Co. Selection depends on supply chain preference and availability.
Q: Is the SA60CAHE3/54 suitable for non-automotive applications?
A: Yes. The SA60CAHE3/54 exceeds standard requirements through AEC-Q101 automotive qualification. It is fully compatible with general-purpose applications and offers enhanced reliability margins. Use this part when automotive-grade quality assurance is beneficial.
Q: What does the suffix (AP, BP, TP) indicate on Micro Commercial Co parts?
A: These suffixes denote packaging and tape configuration options. AP, BP, and TP represent different reel formats and packaging specifications. All three maintain identical electrical performance and are interchangeable from a circuit perspective.
Q: Does the 5.4A peak pulse current on the Taiwan Semiconductor SA60CA affect compatibility?
A: No. The 5.4A rating represents a higher current capability within the same 500W power dissipation limit. This provides additional margin and is fully compatible with circuits designed for the original 5.2A specification.
Q: Are all substitute parts RoHS compliant?
A: The Vishay and Taiwan Semiconductor parts are ROHS3 compliant. Micro Commercial Co parts carry REACH compliance status. Verify specific RoHS requirements for your application and supply chain documentation.
Q: What is the operating temperature range for each substitute?
A: Vishay and Micro Commercial SA60CA variants operate from -55°C to 175°C. Micro Commercial P5KE60CA variants extend to -65°C minimum. Select based on your circuit's thermal environment requirements.
