Product Introduction: LI3803G-VB
LI3803G-VB is a high-performance single N-channel MOSFET in a TO220F package, designed to meet the application requirements of high current and low on-resistance. Its maximum drain-source voltage (VDS) is 30V, which is suitable for a variety of low-voltage power management and switching applications. The gate-source voltage (VGS) of the LI3803G-VB can withstand ±20V and has strong voltage resistance. The gate threshold voltage (Vth) of the device is 1.7V, ensuring that it can be turned on under low voltage conditions. At the same time, its on-resistance (RDS(ON)) is only 4mΩ when VGS is 10V, and it can carry a drain current (ID) of up to 140A, making it excellent in high-power applications.
