Product introduction：
Product Introduction: **Si5511DC-T1-E3-VB** is a high-performance **Dual N-Channel + P-Channel MOSFET** launched by **Vishay**. It adopts **DFN8(3X2)-B** package and is designed for low-voltage, high-efficiency applications. The device supports dual-channel structure, that is, it has **N-Channel** and **P-Channel** configurations at the same time, which is suitable for applications that require reverse control of current direction. Its **VDS** is up to **±20V**, that is, it supports both positive and negative voltages, which can more flexibly meet different power supply voltage requirements. **VGS** The operating voltage is **±8V**, and **Vth** is **0.8V** (N-Channel) and **-0.8V** (P-Channel), respectively, ensuring a lower turn-on voltage, so that it can be driven at a low gate voltage. **RDS(ON)** is **36mΩ** (N-Channel) and **97mΩ** (P-Channel) at **VGS = 4.5V**, and **32mΩ** (N-Channel) and **69mΩ** (P-Channel) at **VGS = 10V**, providing lower on-resistance, thereby reducing power loss and improving system efficiency. The maximum drain current (**ID**) of this MOSFET is **5.9A** (N-Channel) and **-4.1A** (P-Channel), respectively, which is suitable for most low-power load control.
