FS4321-VB Product Introduction
FS4321-VB is a single N-channel MOSFET in TO263 package, designed with advanced Trench technology. The device can withstand drain-source voltage (VDS) up to 150V and gate-source voltage (VGS) of ±20V, with a threshold voltage (Vth) of 3V. With its low on-resistance (RDS(ON)) of 7.5mΩ, FS4321-VB can support drain current (ID) up to 128A at VGS = 10V. This makes it excel in high-current, high-efficiency applications, especially in applications that require fast switching and low energy loss.
