K1821-VB Product Introduction

K1821-VB is a high-performance single N-channel MOSFET in TO220F package, designed for high voltage and medium current applications. Its maximum drain-source voltage (VDS) is 650V, suitable for circuit design requiring high voltage resistance. The maximum drain current (ID) of the device is 2A, which can meet the needs of a variety of electronic devices. The threshold voltage (Vth) of K1821-VB is 3.5V, ensuring that it can be turned on at a lower gate voltage. The on-resistance (RDS(ON)) of this MOSFET is 1700mΩ at VGS of 10V. Although the on-resistance is relatively high, its design can still effectively control energy loss. K1821-VB adopts planar technology, has good thermal management and stability, and is suitable for a variety of industrial and consumer electronic devices.
