Description and Introduction

-12V Single P-Channel HEXFET Power MOSFET in a Micro 3 package The IRLML6401 is a P-channel HEXFET Power MOSFET manufactured by International Rectifier (IR). Below are the key specifications, descriptions, and features from the manufacturer's datasheet:

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

### **Description:**  
The IRLML6401 is a P-channel MOSFET designed for low-voltage, high-speed switching applications. It is optimized for efficiency in power management circuits.  

### **Key Features:**  
- **Voltage Rating (VDSS):** -12V  
- **Current Rating (ID):** -3.7A (continuous)  
- **Low On-Resistance (RDS(on)):**  
  - 0.065Ω (max) @ VGS = -4.5V  
  - 0.085Ω (max) @ VGS = -2.5V  
- **Gate Threshold Voltage (VGS(th)):** -0.7V to -1.4V  
- **Fast Switching Speed:**  
  - Low gate charge (Qg = 8.5nC typical)  
  - Low reverse transfer capacitance (Crss = 20pF typical)  
- **Low Power Loss:** Optimized for high-efficiency applications  
- **Package:** SOT-23 (Surface Mount)  

### **Applications:**  
- Load switching
