Product Introduction
K1728-VB is a high-performance single N-channel MOSFET in SOT89 package, designed for medium voltage and current applications. The device has a drain-source voltage (VDS) of up to 100V, suitable for high-efficiency power management and switching applications. Its maximum drain current is 4.2A, and it has a low on-resistance (RDS(ON) of 125mΩ@VGS=4.5V and 102mΩ@VGS=10V), which can achieve excellent switching performance under the premise of low power consumption and high efficiency. K1728-VB uses Trench technology to enhance its conduction capability and thermal performance, making it an ideal choice for small electronic devices.
