K18N65-VB Product Introduction
K18N65-VB is a 650V single N-channel MOSFET in TO247 package, designed for high voltage and high current applications. The device has a maximum drain current (ID) of 18A and is suitable for use in high power conversion equipment. Its gate-source voltage (VGS) is ±30V and the threshold voltage (Vth) is 3.5V, which can be effectively controlled at relatively high gate voltages. The on-resistance (RDS(ON)) is 430mΩ @ VGS=10V, which can reduce energy loss in the on state. The use of planar technology gives the device good thermal performance, low switching losses and reliability in high voltage environments, making it particularly suitable for power conversion and industrial power applications.
