Product introduction：
Product Introduction:
**SM4373NAKP-VB** is a high-performance **single N-channel MOSFET** in a **DFN8 (5x6)** package, designed for high current and low on-resistance applications. Its maximum drain-source voltage (VDS) is **30V**, the maximum drain current (ID) is **120A**, and it has extremely low on-resistance at different gate-source voltages (VGS). Specifically, **RDS(ON)** is **5mΩ** at **VGS=4.5V** and **3mΩ** at **VGS=10V**. This makes this MOSFET perform well in high-efficiency and low-power loss applications, especially for systems that require fast switching and high current handling. This product uses **Trench technology** to ensure high switching frequency, low switching loss and excellent thermal performance, suitable for a variety of power conversion and power management systems.
