Description and Introduction

Dual P-Channel 30-V (D-S) MOSFET The SI4947ADY is a dual N-channel and P-channel MOSFET manufactured by Vishay Siliconix. Here are the key specifications, descriptions, and features:

### **Specifications:**  
- **Drain-Source Voltage (VDSS):**  
  - N-Channel: 30V  
  - P-Channel: -30V  
- **Continuous Drain Current (ID):**  
  - N-Channel: 6.3A  
  - P-Channel: -5.7A  
- **On-Resistance (RDS(on)):**  
  - N-Channel: 28mΩ (at VGS = 10V)  
  - P-Channel: 50mΩ (at VGS = -10V)  
- **Gate-Source Voltage (VGS):** ±20V  
- **Power Dissipation (PD):** 2.5W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SO-8  

### **Descriptions:**  
- The SI4947ADY is a dual MOSFET combining one N-channel and one P-channel MOSFET in a single SO-8 package.  
- It is designed for high-efficiency power management applications, including DC-DC converters, motor control, and load switching.  

### **Features:**  
- **Low On-Resistance:** Enhances power efficiency.  
- **Fast Switching Speed:** Suitable for high-frequency applications.  
- **Dual Configuration:** Saves board space compared to discrete MOSFETs.  
- **Logic-Level Gate Drive:** Compatible with 5V and 3.3V control signals.  
- **Lead-Free & RoHS Compliant.**
