Product introduction：
1. N4701-VB Product Introduction
N4701-VB is a high-efficiency P-type MOSFET, using **DFN8(3X2)-B** package, designed for low-voltage power management and switching applications. The maximum drain-source voltage (VDS) of the device is **-20V**, and the maximum drain current (ID) can reach **-4A**. At a gate voltage of **4.5V**, its on-resistance (RDS(ON)) is **125mΩ**, and at a gate voltage of **10V**, the on-resistance drops to **90mΩ**. This MOSFET uses **Trench technology**, which provides excellent switching characteristics while reducing conduction losses, and is suitable for the needs of modern low-power electronic devices.
