### **Description:**  
The STB8NA50 is a high-voltage N-channel MOSFET designed for power switching applications. It features low on-resistance, fast switching speeds, and high ruggedness, making it suitable for power supplies, motor control, and other high-voltage applications.  

### **Features:**  
- **High Voltage Capability (500V)**  
- **Low On-Resistance (0.6Ω max)**  
- **Fast Switching Performance**  
- **Avalanche Energy Specified**  
- **Improved dv/dt Capability**  
- **100% Avalanche Tested**  
- **TO-220 Package for Efficient Heat Dissipation**  

The STB8NA50 is commonly used in applications such as:  
- Switch-mode power supplies (SMPS)  
- Motor control circuits  
- Inverters  
- Electronic ballasts  
- High-voltage DC-DC converters  

For detailed electrical characteristics and application notes, refer to the official STMicroelectronics datasheet.
