STT3455-VB MOSFET Product Introduction
STT3455-VB is a single P-channel MOSFET in SOT23-6 package, manufactured based on Trench technology. Its maximum drain-source voltage (VDS) is -30V, and it can carry a maximum drain current of -4.8A, designed for high-efficiency switching applications and low-power systems. This MOSFET has a low on-resistance (RDS(ON)), which is 54mΩ (VGS = 4.5V) and 49mΩ (VGS = 10V), respectively, which makes it exhibit low power loss in high-current applications. Its threshold voltage (Vth) is -1.7V, and it can be started at a lower gate voltage, so it is particularly suitable for low-voltage drive switching applications. STT3455-VB is suitable for use in various electronic devices that require efficient power control, load management and miniaturized design.
