K2857-VB Product Introduction
K2857-VB is a high-performance N-channel MOSFET in a SOT89 package, designed for low voltage and medium current applications. The device has a drain-source voltage (VDS) of up to 60V, suitable for a wide range of electronic devices. The gate-source voltage (VGS) range of K2857-VB is ±20V, and the threshold voltage (Vth) is only 1.7V, ensuring that it turns on quickly under low voltage conditions. The on-resistance (RDS(ON)) has excellent performance, which is 88mΩ @ VGS=4.5V and 76mΩ @ VGS=10V, respectively, showing excellent conduction efficiency, thereby effectively reducing power loss. The maximum continuous current (ID) is 5.5A, and it is manufactured using Trench technology, providing high efficiency and good thermal management performance, suitable for a variety of application scenarios.
