Back to previous pageProduct introduction：
1. K2112-VB Product Introduction
K2112-VB is a high-efficiency single N-channel MOSFET with SOT89 package type, designed for medium voltage applications. The device has a maximum drain-source voltage (VDS) of 100V, suitable for various power management and signal processing circuits. Its threshold voltage (Vth) is 1.8V, which enables switching operation at a lower driving voltage. With its trench technology, K2112-VB achieves low on-resistance (RDS(ON) is 125mΩ@VGS=4.5V and 102mΩ@VGS=10V), significantly improving the energy efficiency of the circuit and reducing power consumption. The maximum drain current (ID) is 4.2A, which enables it to work stably under high load conditions and is an ideal switching solution in modern electronic design.
