Product Introduction: WSF20P03-VB MOSFET
WSF20P03-VB is a high-efficiency P-channel MOSFET that uses advanced Trench technology and is packaged in TO252. The device has a drain-source voltage (VDS) of 30V and a gate-source voltage (VGS) of ±20V, and has a low on-resistance (RDS(ON)) of 25mΩ (VGS=4.5V) and 18mΩ (VGS=10V), respectively. Its maximum drain current (ID) is -40A, which is suitable for applications requiring efficient current control and power management. Its negative drain-source voltage characteristic enables it to perform well in scenarios such as reverse current control, load switching, and inverters. WSF20P03-VB is an ideal switching element in high-performance power management systems, especially for low-voltage, high-current applications.
