Description and Introduction

Dual P-Channel E nhancement Mode Field Effect Transistor The STM4953 is a P-channel MOSFET manufactured by STMicroelectronics (STMHOP). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Drain-Source Voltage (VDS):** -30V  
- **Gate-Source Voltage (VGS):** ±20V  
- **Continuous Drain Current (ID):** -4.5A  
- **Pulsed Drain Current (IDM):** -18A  
- **Power Dissipation (PD):** 2.5W  
- **On-Resistance (RDS(on)):** 70mΩ (max) at VGS = -10V  
- **Threshold Voltage (VGS(th)):** -1V to -3V  

### **Descriptions:**
- The STM4953 is a P-channel enhancement-mode power MOSFET designed for low-voltage, high-speed switching applications.  
- It is commonly used in power management, DC-DC converters, and load switching circuits.  
- The device is housed in a TO-252 (DPAK) package for efficient thermal performance.  

### **Features:**
- **Low On-Resistance:** Ensures minimal power loss.  
- **Fast Switching Speed:** Suitable for high-frequency applications.  
- **Avalanche Energy Specified:** Enhances reliability in rugged conditions.  
- **Logic-Level Gate Drive:** Compatible with 5V and 3.3V control signals.  
- **Lead-Free & RoHS Compliant:** Meets environmental standards.
