**Product Introduction: STU448S-VB**
STU448S-VB is a high-efficiency single N-type MOSFET in TO252 package, designed to handle high current applications and achieve low power loss. Its maximum drain-source voltage (VDS) is 40V, the gate-source threshold voltage (Vth) is 2.5V, and the maximum drain current (ID) is 55A. The on-resistance of STU448S-VB is 14mΩ at VGS=4.5V and 12mΩ at VGS=10V. This makes this MOSFET excellent in applications such as power management, power conversion, and motor drive that require high efficiency and high reliability. Using Trench technology, it is able to maintain low on-resistance and reduce power loss in high-frequency switching operations, and is particularly suitable for high-power power systems and industrial control equipment.
