1. K4078B-ZK-VB Product Introduction
K4078B-ZK-VB is a high-performance single N-channel MOSFET in TO252 package, designed for low voltage and high current applications. Its drain-source voltage (VDS) reaches 40V, which can support ±20V gate-source voltage (VGS), ensuring stability under various working conditions. The gate threshold voltage (Vth) of the device is 2.5V, providing fast switching response capability. In the on state, the drain-source on-resistance (RDS(ON)) of K4078B-ZK-VB is 6mΩ (@ VGS=4.5V) and 5mΩ (@ VGS=10V), making it excellent in power loss and suitable for high-efficiency power supply applications. The maximum drain current (ID) of the device is 85A, which is very suitable for occasions that require high current handling. The trench technology is used to further improve its switching speed and conduction performance.
