Product Introduction: WTK4228-VB MOSFET
WTK4228-VB is a dual N-channel MOSFET in SOP8 package, designed for low voltage, high current and high efficiency power management systems. It has two N-channel MOSFET transistors, which can provide dual functions in high efficiency power switching and current control applications. The MOSFET has a rated drain-source voltage (VDS) of 30V, a gate-source voltage (VGS) of ±20V, a threshold voltage (Vth) of 1.7V, supports a large current (ID=8.5A) and has an extremely low on-resistance. Its RDS(ON) is 20mΩ at VGS=4.5V and 16mΩ at VGS=10V, which greatly reduces switching losses and improves system efficiency. WKT4228-VB uses advanced Trench technology, which can provide excellent performance in various high frequency and high current applications, ensuring low power consumption and stable current transmission.
This MOSFET is particularly suitable for current regulation, load switching, power management, DC-DC converters and other energy management modules that require a dual N-channel configuration. Its low on-resistance and high current carrying capacity make it widely used in various power electronics fields, suitable for systems such as consumer electronics, LED drivers, battery management and automotive electronics.
