Product introduction：
STS12NH3LL-VB MOSFET Product Introduction
STS12NH3LL-VB is a unipolar N-channel MOSFET in SOP8 package, manufactured with advanced Trench technology, with low on-resistance (RDS(ON)) and excellent switching characteristics, suitable for high-efficiency power control and switching applications. The drain-source voltage (VDS) of this MOSFET is 30V, the gate-source voltage (VGS) is ±20V, and the maximum drain current (ID) is 13A, which can meet the requirements of high-power and high-frequency applications. Its threshold voltage (Vth) is 1.7V, ensuring that it can be turned on at a lower gate voltage, providing greater control flexibility. The low RDS(ON) value of this MOSFET (maximum 8mΩ at VGS = 10V) enables it to reduce power losses and improve thermal management capabilities in high-efficiency applications.
