- **Package:** DO-214AC (SMA)  
- **Mounting Type:** Surface Mount  
- **RoHS Compliant:** Yes  

### **Descriptions:**  
- Designed to protect sensitive electronics from **transient voltage surges** (ESD, lightning, inductive switching).  
- **Bi-directional** TVS diode, clamping voltage in both polarities.  
- **Low leakage current** and **fast response time**.  

### **Features:**  
- **High surge capability** (400W peak pulse power).  
- **Automotive-grade reliability** (AEC-Q101 qualified).  
- **Low clamping voltage** for effective protection.  
- **Pb-free and halogen-free** construction.  

This device is commonly used in **power supplies, communication lines, automotive systems, and industrial applications** for transient voltage protection.
