Description and Introduction

N-CHANNEL 30V The STP55NF03L is an N-channel Power MOSFET manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:  

### **Manufacturer:** STMicroelectronics  

### **Specifications:**  
- **Drain-Source Voltage (VDS):** 30V  
- **Continuous Drain Current (ID):** 55A  
- **Pulsed Drain Current (IDM):** 220A  
- **Power Dissipation (PD):** 75W  
- **Gate-Source Voltage (VGS):** ±20V  
- **On-Resistance (RDS(on)):**  
  - 0.018Ω (max) at VGS = 10V  
  - 0.022Ω (max) at VGS = 4.5V  
- **Threshold Voltage (VGS(th)):** 1-3V  
- **Total Gate Charge (Qg):** 50nC (typical)  
- **Operating Junction Temperature (TJ):** -55°C to 175°C  

### **Description:**  
The STP55NF03L is a low-voltage, high-current N-channel MOSFET designed for power management applications. It features low on-resistance and fast switching performance, making it suitable for DC-DC converters, motor control, and power switching circuits.  

### **Features:**  
- **Low On-Resistance (RDS(on))** for reduced conduction losses  
- **High Current Capability** (55A continuous, 220A pulsed)  
- **Fast Switching Speed** for efficient power conversion  
- **Avalanche Energy Specified** for ruggedness in inductive loads  
- **100% Avalanche Tested** for reliability  
- **Low Gate Charge** for improved drive efficiency  
- **Lead-Free and RoHS Compliant**  

The device is available in a TO-220 package for easy mounting and thermal management.
