Description and Introduction

Single N-Channel/ Logic Level/ PowerTrench MOSFET The SI4822 is a P-Channel MOSFET manufactured by Siliconix (a subsidiary of Vishay). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Drain-Source Voltage (VDSS):** -20V  
- **Gate-Source Voltage (VGS):** ±12V  
- **Continuous Drain Current (ID):** -4.3A (at TC = 25°C)  
- **Pulsed Drain Current (IDM):** -17A  
- **Power Dissipation (PD):** 1.25W (at TA = 25°C)  
- **On-Resistance (RDS(ON)):**  
  - 0.065Ω (at VGS = -4.5V, ID = -3.7A)  
  - 0.085Ω (at VGS = -2.5V, ID = -2.5A)  
- **Threshold Voltage (VGS(th)):** -0.5V to -1.5V  
- **Total Gate Charge (Qg):** 9nC (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**
The SI4822 is a P-Channel enhancement-mode MOSFET designed for low-voltage, high-performance switching applications. It features low on-resistance and fast switching speeds, making it suitable for power management in portable electronics, battery protection circuits, and DC-DC converters.

### **Features:**
- **Low On-Resistance:** Minimizes conduction losses.  
- **Fast Switching:** Optimized for high-efficiency power conversion.  
- **Small Footprint:** Available in SOT-23 and other compact packages.  
- **Logic-Level Gate Drive:** Compatible with 2.5V and 3.3V logic.  
- **Avalanche Energy Rated:** Enhances reliability in inductive load applications.
