Product Introduction
K3122-VB is a high-performance single N-channel MOSFET designed in SOT89 package, designed for miniaturization and high-efficiency power management. Its maximum drain-source voltage (VDS) is 30V, and the gate-source voltage (VGS) can reach ±20V. The threshold voltage (Vth) of K3122-VB is 1.7V, ensuring that it turns on quickly at low voltage. The on-resistance (RDS(ON)) is 30mΩ and 22mΩ at gate-source voltages of 2.5V and 4.5V respectively. The low on-resistance helps achieve high efficiency under high current conditions. The maximum drain current (ID) can reach 6.8A, which is suitable for power management and switching applications of various small electronic devices.
