Description and Introduction

30V Dual N-Channel HEXFET Power MOSFET in a Micro 8 package The IRF7503 is a power MOSFET manufactured by International Rectifier (IR). Below are the manufacturer's specifications, descriptions, and features:  

### **Manufacturer Specifications:**  
- **Manufacturer:** International Rectifier (IR)  
- **Type:** N-Channel Power MOSFET  
- **Voltage Rating (VDSS):** 30V  
- **Current Rating (ID):** 140A (at 25°C)  
- **RDS(on) (Max):** 3.5 mΩ (at VGS = 10V)  
- **Gate-Source Voltage (VGS):** ±20V  
- **Power Dissipation (PD):** 200W (at 25°C)  
- **Package:** TO-220AB  

### **Descriptions:**  
The IRF7503 is a high-current, low-on-resistance N-Channel MOSFET designed for power management applications. It is optimized for high-efficiency switching in power supplies, motor control, and DC-DC converters.  

### **Features:**  
- Low on-resistance (RDS(on)) for reduced conduction losses  
- High current handling capability  
- Fast switching performance  
- Improved dv/dt capability  
- Avalanche energy specified  
- Lead-free and RoHS compliant  

This information is based on the manufacturer's datasheet. For detailed performance curves and application notes, refer to the official IRF7503 datasheet.
