K2991-VB Product Introduction
K2991-VB is a high voltage N-channel MOSFET in TO220F package, designed for applications requiring high voltage and medium current. The device has a drain-source voltage (VDS) of up to 650V, suitable for use in high voltage environments, and a gate-source voltage (VGS) range of ±30V, making it adaptable to various drive circuits. Its threshold voltage (Vth) is 3.5V, allowing effective switching at lower gate voltages. The on-resistance (RDS(ON)) of K2991-VB is 1100mΩ @ VGS=10V, which is relatively high, but still ensures good efficiency in high-voltage applications. The maximum continuous current (ID) is 7A, making it suitable for applications requiring medium current handling capabilities. K2991-VB uses planar technology (Plannar), which ensures its stability and reliability under various working conditions and is widely used in power management and industrial control.
