Product Introduction
**WST3400-VB** is a single N-channel MOSFET in a **SOT23-3** package, designed for low voltage and high-efficiency switching applications. It has efficient current conduction capability and low on-resistance, suitable for low-power systems, especially in application scenarios where high current needs to be controlled. The maximum drain-source voltage (VDS) of WST3400-VB is 30V, and the maximum gate-source voltage (VGS) is ±20V, which can adapt to a wide range of voltage requirements. The turn-on voltage (Vth) of this MOSFET is 1.7V, allowing it to start working at a low gate voltage. As the gate voltage increases, its on-resistance (RDS(ON)) will further decrease from 33mΩ (VGS = 4.5V) to 30mΩ (VGS = 10V), making current conduction more efficient. The maximum drain current (ID) of this product is 6.5A, suitable for a variety of applications requiring high switching performance and low power consumption.
