- **Drain-Source Voltage (VDS):** -20V  
- **Gate-Source Voltage (VGS):** ±12V  
- **Continuous Drain Current (ID):** -5.3A  
- **Pulsed Drain Current (IDM):** -20A  
- **Power Dissipation (PD):** 2.5W  
- **On-Resistance (RDS(on)):** 0.06Ω (max) at VGS = -10V  
- **Threshold Voltage (VGS(th)):** -1V to -3V  
- **Total Gate Charge (Qg):** 12nC (typical)  
- **Package:** SO-8  

### **Descriptions:**
- A **P-Channel** enhancement-mode MOSFET designed for **low-voltage, high-efficiency switching applications**.  
- Optimized for **power management** in portable electronics, battery protection, and load switching.  
- Features **low on-resistance** and **fast switching speeds**.  

### **Features:**
- **Low RDS(on)** for reduced conduction losses.  
- **High current handling** capability in a compact SO-8 package.  
- **Fast switching performance** for efficient power conversion.  
- **Logic-level compatible** gate drive (fully enhanced at -4.5V).  
- **Avalanche energy rated** for ruggedness in inductive load applications.  

This information is based on the manufacturer's datasheet and product documentation. For detailed electrical characteristics, refer to the official datasheet.
