- **Package:** SOD-323 (SC-76)  

### **Description:**  
The **SP1491EEN-L** is a unidirectional TVS diode designed to protect sensitive electronics from transient voltage events such as ESD (Electrostatic Discharge), lightning, and other voltage surges. It offers low clamping voltage and fast response time, making it suitable for high-speed data line protection.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (typically <1ns).  
- **ESD Protection:** Meets IEC 61000-4-2 (Level 4) standards (±30kV air, ±30kV contact).  
- **Compact Package:** SOD-323 (SC-76) footprint for space-constrained applications.  
- **High Surge Capability:** Handles high transient currents.  

This information is strictly based on the manufacturer's datasheet and product documentation.
