Product introduction：
1. MI8618-VB Product Introduction
MI8618-VB is a **single N-channel MOSFET** in **DFN8(3X3)** package, designed for high-efficiency low-voltage applications. Its **maximum drain-source voltage (VDS)** is 30V, and **gate-source voltage (VGS)** is ±20V, supporting flexible applications in a variety of circuit environments. **The threshold voltage (Vth) is 1.7V**, ensuring fast response at lower drive voltages. The **on-resistance (RDS(ON))** of the device is 19mΩ at VGS = 4.5V and only 13mΩ at VGS = 10V, which helps reduce conduction losses. MI8618-VB has a **maximum drain current (ID)** of 30A, combined with **Trench technology**, to provide excellent switching performance and high efficiency.
