LI3103-VB Product Introduction
**LI3103-VB** is a high-efficiency single N-channel MOSFET in a TO220F package, designed for medium voltage and high current applications. The device has a **drain-source voltage (VDS)** of 30V, suitable for various power management and switch control applications. The maximum **drain current (ID)** is 68A, which can support high-load operation and ensure stability under dynamic load conditions. The **gate-source voltage (VGS)** range is ±20V, providing flexible drive options. The **threshold voltage (Vth)** is 1.7V, ensuring reliable conduction at lower voltages. When the **VGS is 10V**, the **on-resistance (RDS(ON)** of this MOSFET is only 1mΩ, which greatly reduces power consumption and improves the overall efficiency of the system. It is particularly suitable for applications that require high efficiency and low heat dissipation.
