TM9435AS FS-VB MOSFET Product Introduction
TM9435AS FS-VB is a high-performance single P-channel MOSFET in SOP8 package, designed for low-voltage, high-efficiency switching applications. With a maximum drain-source voltage (VDS) of -30V, this model is suitable for a variety of low-voltage power management and power control systems. The on-resistance (RDS(ON)) of TM9435AS FS-VB is 56mΩ (VGS = 4.5V) and 33mΩ (VGS = 10V), respectively, providing a drain current (ID) of up to 5.8A, and using Trench technology to optimize performance and reduce power loss. Its threshold voltage (Vth) is -1.7V, which is suitable for low-voltage drive systems, ensuring smooth turn-on at a lower gate-source voltage.
This MOSFET has low on-resistance and high current carrying capacity, suitable for applications requiring efficient power conversion and low heat generation. It is widely used in battery management, power switching, load control and other fields, and is particularly suitable for use in reverse current control and current regulation systems.
