Back to previous pageProduct introduction：
1. K3157-VB Product Introduction
K3157-VB is a single N-channel MOSFET in a TO220F package with a drain-source voltage (VDS) of 200V, suitable for high voltage and medium-to-high current switching applications. Its gate-source voltage (VGS) is ±20V, which can provide a robust gate drive tolerance. The gate threshold voltage (Vth) of the device is 3V, ensuring its stable turn-on at a higher gate voltage. Its on-resistance (RDS(ON)) is 58mΩ@VGS=10V, which can effectively reduce power consumption and heat generation, and is suitable for applications such as high-efficiency power conversion and motor drive. K3157-VB uses Trench technology to improve its power density and heat dissipation performance, making it suitable for use in a variety of industrial and power electronics fields.
