SI4124DY-T1-E3 Product Introduction
**SI4124DY-T1-E3** is a single N-channel MOSFET in SOP8 package, using advanced Trench technology, designed for high-efficiency power management and switching applications. Its maximum drain-source voltage (V_DS) is 40V, and the maximum gate-source voltage (V_GS) is ±20V. This MOSFET has a very low on-resistance (R_DS(ON)), which is 6mΩ at V_GS=4.5V and 4mΩ at V_GS=10V, thereby providing higher current transfer efficiency and reducing power loss. The maximum drain current (I_D) is 18A, which is suitable for high current scenarios. Its threshold voltage (V_th) is 3V, which is suitable for applications requiring high-efficiency switching control, and can provide stable and reliable performance in various industrial, consumer electronics, automotive and communications fields.
