Description and Introduction

Intelligent Power Module. Gate Driver IC integrated with a half bridge FredFET Designed for sub 180W Motor Drive applications The IR3103 is a power MOSFET manufactured by International Rectifier (IR). Below are the key specifications, descriptions, and features from the manufacturer's datasheet:

### **Manufacturer:** International Rectifier (IR)  
### **Part Number:** IR3103  

### **Description:**  
The IR3103 is a **N-Channel Power MOSFET** designed for high-performance switching applications. It is optimized for low on-resistance and fast switching speeds, making it suitable for power management, motor control, and DC-DC converters.  

### **Key Features:**  
- **Voltage Rating:** 30V  
- **Current Rating:** 100A (continuous drain current)  
- **On-Resistance (RDS(on)):** Typically 3.3 mΩ (at VGS = 10V)  
- **Gate Threshold Voltage (VGS(th)):** 1V to 2.5V  
- **Fast Switching Speed:** Low gate charge (Qg) for efficient high-frequency operation  
- **Avalanche Energy Rated:** Enhances ruggedness in inductive load applications  
- **Low Profile Package:** TO-220AB (through-hole) for easy mounting  

### **Applications:**  
- DC-DC converters  
- Motor drives  
- Power supplies  
- Synchronous rectification  

### **Datasheet Reference:**  
For detailed electrical characteristics and thermal performance, refer to the official IR3103 datasheet from International Rectifier.  

(Note: Always verify specifications with the latest datasheet as parameters may vary slightly between revisions.)
