WST2011-VB MOSFET Product Introduction
**WST2011-VB** is a **dual P-channel MOSFET**, using **SOT23-6** package, suitable for high-performance, low-power loss electronic circuits. The maximum drain-source voltage (VDS) of this MOSFET is **-20V**, the maximum drain current (ID) is **-4A**, and it uses **Trench** technology to provide extremely low on-resistance (RDS(ON)). When **VGS = 4.5V**, RDS(ON) is **75mΩ**, and when **VGS = 2.5V**, it is **100mΩ**, which can effectively reduce power loss and improve system efficiency. Its **Vth** (threshold voltage) is **-0.6V**, which ensures that the MOSFET can work normally at low gate voltage, which is very suitable for various low-voltage and low-power applications.
