Description and Introduction

30V Single N-Channel HEXFET Power MOSFET in a Super 220 (TO-273AA) package The IRLBA3803P is a power MOSFET manufactured by International Rectifier (IR). Below are the key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Drain-Source Voltage (VDSS):** 30V  
- **Continuous Drain Current (ID):** 140A (at 25°C)  
- **Pulsed Drain Current (IDM):** 560A  
- **Gate-Source Voltage (VGS):** ±20V  
- **Power Dissipation (PD):** 300W (at 25°C)  
- **On-Resistance (RDS(on)):** 3.8mΩ (max at VGS = 10V)  
- **Threshold Voltage (VGS(th)):** 1.0V (min) to 2.0V (max)  
- **Input Capacitance (Ciss):** 5200pF (typical)  
- **Operating Junction Temperature (TJ):** -55°C to +175°C  

### **Description:**
The IRLBA3803P is a **N-channel HEXFET® Power MOSFET** designed for high-current, low-voltage applications. It is optimized for **high efficiency and fast switching performance** in power management circuits, motor control, and DC-DC converters.

### **Features:**
- **Advanced Process Technology** for low on-resistance and high current handling.  
- **Ultra-Low RDS(on)** for reduced conduction losses.  
- **Fast Switching Speed** for improved efficiency in high-frequency applications.  
- **Avalanche Energy Rated** for ruggedness in demanding environments.  
- **Fully Characterized for Linear Mode Operation** (suitable for linear applications).  
- **Pb-Free and RoHS Compliant** for environmental safety.  

This MOSFET is commonly used in **automotive, industrial, and power supply applications** where high power density and reliability are required.  

For detailed datasheet information, refer to the official IR documentation.

Application Scenarios & Design Considerations

30V Single N-Channel HEXFET Power MOSFET in a Super 220 (TO-273AA) package

Alternative Part Number

  • FDP8870 --: N-channel logic-level MOSFET in TO-220 with comparable low RDS(on) and current rating, suitable drop-in replacement for switching applications.
  • STP75NF75 --: 75A 75V N-channel MOSFET in TO-220, similar voltage and current class, widely available and cost effective.
  • IRFZ44N --: Popular logic-level N-channel MOSFET in TO-220 with 55V rating, adequate for many lower-voltage substitutions where 30V margin is acceptable.
