STU456S-VB MOSFET Product Introduction
STU456S-VB is a single N-channel MOSFET in TO252 package, designed for high current and high efficiency applications. Its maximum drain-source voltage (VDS) is 40V, and the maximum drain current (ID) can reach 55A, which is suitable for applications requiring low power loss and high current carrying capacity. This MOSFET uses Trench technology and has excellent conduction characteristics. When VGS=10V, the on-resistance (RDS(ON)) is as low as 12mΩ, which can significantly reduce the energy loss during the switching process and ensure efficient operation of the system.
STU456S-VB is widely used in power management, power control, power tool drive and battery management. It is suitable for current-intensive application scenarios, especially for power conversion systems and drive modules that require low on-resistance and high current carrying capacity.
