### **Package:**  
- **Type:** PQFN 5x6mm  
- **Termination:** Lead-free, RoHS compliant  

### **Description:**  
The IRF7471 is a high-performance N-channel power MOSFET designed for high-current, low-voltage applications. It features ultra-low on-resistance (RDS(on)) and fast switching characteristics, making it suitable for power management in DC-DC converters, motor control, and synchronous rectification.  

### **Features:**  
- **Low RDS(on)** for reduced conduction losses  
- **High current handling capability**  
- **Optimized for high-frequency switching**  
- **Avalanche energy rated**  
- **Lead-free and RoHS compliant**  
- **Improved thermal performance** due to PQFN package  

This information is based solely on the manufacturer's datasheet.
