### **Description:**
The **STP3NB80** is an N-channel **800V** power MOSFET designed for high-voltage switching applications. It is optimized for **low gate charge** and **fast switching performance**, making it suitable for power supplies, inverters, and motor control circuits.

### **Features:**
- **High voltage capability (800V)**  
- **Low on-resistance (RDS(on))**  
- **Fast switching speed**  
- **Low gate charge**  
- **Avalanche ruggedness**  
- **100% avalanche tested**  
- **TO-220 package for efficient heat dissipation**  

This MOSFET is commonly used in **switched-mode power supplies (SMPS), lighting, and industrial applications** where high voltage and efficiency are required.
