Product Introduction
**WST2303S-VB** is a single P-channel MOSFET in SOT23-3 package. It is based on Trench technology and has low on-resistance and high efficiency. It is designed for low voltage, high power switching applications. The maximum drain-source voltage (VDS) of this MOSFET is -20V, and the maximum gate-source voltage (VGS) is ±12V. It is suitable for applications that require low voltage and high load current. Its on-resistance (RDS(ON)) is 80mΩ at VGS = 2.5V and drops to 60mΩ at VGS = 10V, which makes the WST2303S-VB have low power loss and excellent current switching performance, with a maximum drain current (ID) of -4A. Due to its compact SOT23-3 package and efficient switching characteristics, the WST2303S-VB is suitable for multiple applications such as portable electronic devices, battery management systems, and low-power switching power supplies.
