Product introduction：
Product Introduction
**SM1A63NHK-VB** is a unipolar **N-Channel MOSFET** in **SOP8** package, with high-performance switching characteristics and low on-resistance. Its **VDS (drain-source voltage)** is **100V**, which is suitable for power management, switching power supplies, load switches and other fields in the medium voltage range. The gate drive voltage **VGS** of this device is **±20V**, which is suitable for most common drive circuits. **Vth (turn-on voltage)** is **2.5V**, which enables the MOSFET to start conducting at a lower gate voltage and optimizes the switching characteristics.
SM1A63NHK-VB adopts **Trench technology**, which enables it to have a low **RDS(ON)** of **8mΩ** when turned on (at **VGS=10V**), thereby effectively reducing power consumption and improving system efficiency. With a maximum current of **15.5A**, the device can handle higher load currents and is suitable for a variety of high-efficiency power supply and switch control applications.
