Product Introduction
**UTT4815L-S08-R-VB** is a **single P-channel MOSFET**, which adopts **SOP8 package**, and has **maximum drain-source voltage (VDS) of -30V** and **maximum drain current (ID) of -9A**. This MOSFET adopts advanced **Trench technology**, which provides low on-resistance (**RDS(ON)**) and high efficiency at a lower gate voltage, and is suitable for high-efficiency power conversion applications such as power management, switching power supplies and load switches. Its **lowest RDS(ON)** value (18mΩ at **VGS = 10V**) and **threshold voltage (Vth) of -1.7V** suitable for low-voltage control systems make it excellent in power control and energy management systems.
This MOSFET is particularly suitable for applications that require load switching, negative power control and power conversion, especially in switch control in **negative power circuits**, **battery management systems (BMS)** and **intelligent power modules**.
