Product Introduction — K811-VB MOSFET
K811-VB is a high-performance unipolar N-channel MOSFET in TO220F package with a maximum drain-source voltage of 100V and a gate-source voltage tolerance of ±20V. Its threshold voltage is 1.8V, which enables effective conduction at a lower gate voltage. K811-VB uses Trench process technology, providing low on-resistance (RDS(ON) is 86mΩ@VGS=10V) and capable of carrying up to 18A of drain current. This MOSFET is ideal for efficient power management and switching applications, designed to meet the needs of modern electronic devices for efficient and reliable performance.
