SPN4346S8RG-VB MOSFET Product Introduction
SPN4346S8RG-VB is a high-performance N-channel MOSFET in SOP8 package, designed for low-voltage and high-efficiency switching applications. This MOSFET has a drain-source withstand voltage (VDS) of 30V, suitable for low-voltage drive and low-power power management applications. Its gate threshold voltage (Vth) is 1.7V, which means it can be activated at a lower gate voltage. The on-resistance (RDS(ON)) of SPN4346S8RG-VB is very low, 11mΩ@VGS=4.5V and 8mΩ@VGS=10V, respectively, which can significantly reduce power losses under high current operating conditions. The maximum drain current is 13A, which is suitable for high-efficiency power conversion, power amplification and switching applications. This MOSFET uses Trench technology to provide excellent switching performance and lower conduction losses, suitable for use in low-voltage systems requiring high efficiency and reliability.
