1. K4078-ZK-E1-VB Product Introduction
K4078-ZK-E1-VB is a high-performance single N-channel MOSFET in TO252 package. It has the advantages of low on-resistance and high current carrying capacity, and is designed for high-efficiency power management applications. Its maximum drain-source voltage (VDS) is 40V, the rated range of gate-source voltage (VGS) is ±20V, and the threshold voltage (Vth) is 2.5V, ensuring reliable startup under low gate voltage conditions. The device has an on-resistance (RDS(ON)) of 5mΩ at VGS=10V and 6mΩ at VGS=4.5V, and a drain current (ID) of up to 85A, which can cope with high current requirements. With Trench technology, K4078-ZK-E1-VB provides excellent switching performance and thermal efficiency, and is very suitable for industrial control, consumer electronics, and automotive electronics.
