K5A45DAA4-VB Product details
Back to previous pageProduct introduction：
1. Product Introduction
K5A45DAA4-VB is an N-channel power MOSFET in TO220F package, designed for high-voltage applications. The device has a maximum drain-source voltage (VDS) of 650V and has the ability to handle high-voltage environments, making it very suitable for industrial-grade power supplies and control circuit applications. Its threshold voltage (Vth) is 3.5V, ensuring reliable startup at a lower drive voltage. The on-resistance (RDS(ON)) of K5A45DAA4-VB is 2560mΩ (at VGS of 10V). Although the on-resistance is high, it is suitable for low-power applications. Its maximum drain current (ID) is 4A, and using Plannar technology, the device has good thermal stability and reliability, and is suitable for applications with long working hours.
