Description and Introduction

30V Single N-Channel HEXFET Power MOSFET in a TO-220AB package The IRL3803 is a power MOSFET manufactured by International Rectifier (IR). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
International Rectifier (IR)  

### **Description:**  
The IRL3803 is an N-channel HEXFET® power MOSFET designed for high-efficiency switching applications. It is optimized for low gate drive power and fast switching speeds.  

### **Key Features:**  
- **Drain-Source Voltage (VDSS):** 30V  
- **Continuous Drain Current (ID):** 140A (at 25°C case temperature)  
- **Pulsed Drain Current (IDM):** 560A  
- **RDS(on) (Max):** 6.0 mΩ (at VGS = 10V)  
- **Gate-Source Voltage (VGS):** ±20V  
- **Power Dissipation (PD):** 200W (at 25°C case temperature)  
- **Avalanche Energy (EAS):** 1.1J  
- **Low Gate Charge (Qg):** 150nC (typical)  
- **Fast Switching Speed**  
- **TO-220AB Package**  
- **Fully Avalanche Rated**  
- **Applications:** Switching regulators, motor control, DC-DC converters, and power management circuits  

### **Additional Notes:**  
- The IRL3803 is part of IR's HEXFET® family, known for high efficiency and ruggedness.  
- It is designed to minimize conduction and switching losses.  

This information is based on the manufacturer's datasheet and product specifications.

Application Scenarios & Design Considerations

30V Single N-Channel HEXFET Power MOSFET in a TO-220AB package

Alternative Part Number

  • IRF3205 --: N-channel MOSFET with comparable 55V/110A ratings and low RDS(on), widely used as a drop-in substitute for the IRL3803 in switching applications.
  • STP75NF75 --: 75V N-channel power MOSFET with similar current capability and low on-resistance, suitable replacement in motor drive and power supply circuits.
  • FDP047AN08A0 --: 80V N-channel MOSFET with low RDS(on) and high current rating, offering comparable performance for the IRL3803 in power switching designs.
