### **Descriptions:**  
- Designed for **ESD and surge protection** in **low-voltage circuits**.  
- **Uni-directional** (polarized) TVS diode, meaning it clamps voltage in one direction.  
- Suitable for **automotive, industrial, and consumer electronics** applications.  

### **Features:**  
- **Fast response time** (sub-nanosecond) for transient suppression.  
- **Low clamping voltage** for effective protection.  
- **High surge capability** (400W peak pulse power).  
- **RoHS compliant** (lead-free).  
- **AEC-Q101 qualified** for automotive applications.  

This diode is commonly used in **power supplies, communication ports, and data lines** to prevent damage from voltage spikes.
