UK3019-VB MOSFET Product Introduction
UK3019-VB is a unipolar N-type MOSFET in SOT23-3 package, designed for miniaturization and low power applications. Its maximum drain-source voltage (V_DS) is 60V, suitable for medium and low voltage power supply circuits. The gate-source voltage (V_GS) of this device can reach ±20V, with a low on-resistance, which can effectively reduce conduction losses. The on-resistance (R_DS(ON)) of UK3019-VB is 2800mΩ when V_GS is 10V, which is suitable for lower current applications with a maximum leakage current of 0.3A. This MOSFET adopts advanced Trench technology to provide better switching performance and is widely used in communications, power management and low-power power modules.
