Product introduction：
STL8NH3LL-VB MOSFET Product Introduction
STL8NH3LL-VB is a single N-type MOSFET in DFN8 (3X3) package with high efficiency and low on-resistance. Its maximum drain-to-source voltage (VDS) is 30V, suitable for low-voltage, high-power density electronic products and power management systems. The on-resistance (RDS(ON)) of this MOSFET is very low, 19mΩ (VGS = 4.5V) and 13mΩ (VGS = 10V), making it extremely efficient in high-current switching applications. With a maximum drain current of 30A, it is suitable for applications requiring high efficiency and high current carrying capacity such as motor drives, battery management, and switching power supplies. Manufactured using Trench technology, it has excellent switching characteristics and can achieve lower power losses under high-frequency operating conditions.
