Product Introduction: SFR9120TF-VB
SFR9120TF-VB is a high-performance P-channel MOSFET in TO252 package, designed for applications requiring medium-to-high voltage and medium-current load control. Its maximum drain-to-source voltage (V_DS) is -100V, which can adapt to high-voltage power systems. The gate-to-source voltage (V_GS) of this MOSFET is ±20V, providing a flexible control range. It has a low on-resistance (R_DS(on)) of 280mΩ (V_GS=4.5V) and 250mΩ (V_GS=10V), making it more efficient in switching applications. The maximum drain current (I_D) is -8.8A, and Trench technology is used to provide lower conduction losses and improve efficiency. SFR9120TF-VB can be widely used in power management, battery protection, electric drive and other fields, especially in environments requiring high voltage resistance and low power consumption.
