Working Principles

The SI4423DY-T1-GE3 operates as a switch in electronic circuits, controlling the flow of current based on the voltage applied to its gate terminal. When a sufficient voltage is applied to the gate, the MOSFET allows current to flow between the drain and source terminals, effectively acting as a closed switch. Conversely, when the gate voltage is below the threshold, the MOSFET behaves as an open switch, interrupting the current flow.
