Product Introduction
WTK4501-VB is a high-performance dual N+P channel MOSFET in SOP8 package, designed for low voltage, high-efficiency power management, battery management and load control. The product operates at a drain-source voltage of ±30V and is suitable for various power conversion and switching applications. Its threshold voltage (Vth) is 1.6V and -1.7V, respectively, providing good current regulation performance.
At VGS=10V, the on-resistance of the N-channel MOSFET is 18mΩ, and the on-resistance of the P-channel MOSFET is 40mΩ, making it excellent in high-efficiency power management. Its maximum drain current (ID) is ±8A, which is suitable for low-power load switching and power conversion fields, can effectively reduce power loss, and improve system efficiency.
Due to the use of Trench technology, the WTK4501-VB has a lower on-resistance and higher switching speed, which is particularly suitable for applications requiring high performance and low power consumption. Its dual MOSFET structure makes it very useful in power management circuits, enabling higher switching density and finer current control.
