Product Introduction
**WST2339-VB** is a single P-channel MOSFET in a small **SOT23-3** package, suitable for low-voltage, high-efficiency switching applications. This MOSFET has a low on-resistance, which can effectively reduce power loss during current transmission. The maximum drain-source voltage (VDS) of WST2339-VB is -12V, and the maximum gate-source voltage (VGS) is ±12V, which is suitable for low-voltage power switching applications. Its turn-on voltage (Vth) is -0.8V, which can be turned on at a lower gate-source voltage. As the gate voltage increases, its on-resistance (RDS(ON)) will further decrease from 40mΩ (VGS = 2.5V) to 18mΩ (VGS = 10V), making this product perform well in high-efficiency systems, with a maximum drain current (ID) of -6A. The WST2339-VB is a high performance, low power, compact MOSFET ideal for mobile devices, low power supplies, battery management and other precision circuit applications.
