K4019-VB Product Introduction
K4019-VB is a high-efficiency unipolar N-channel MOSFET in TO252 package. This MOSFET has a high drain-source voltage (VDS) of 100V, suitable for a variety of power management and switching applications. Its gate-source voltage (VGS) is ±20V, ensuring that it is turned on stably and reliably under different operating conditions. The threshold voltage (Vth) of K4019-VB is 1.8V, combined with its low on-resistance (RDS(ON)), which is 57mΩ @ VGS=4.5V and 55mΩ @ VGS=10V respectively, giving the device significant advantages in power loss and heat management. Using advanced Trench technology, K4019-VB has excellent switching characteristics and thermal performance, making it ideal for use in high-efficiency electronic devices.
