K4078-ZK-VB Product Introduction
K4078-ZK-VB is a single N-channel MOSFET in TO252 package, suitable for high current, low voltage applications. It can withstand drain-source voltage (VDS) up to 40V and gate-source voltage (VGS) of ±20V, and has a threshold voltage (Vth) of 2.5V, which can achieve efficient conduction at a lower gate voltage. At 4.5V gate-source voltage, the on-resistance (RDS(ON)) is 6mΩ, and at 10V gate-source voltage it is only 5mΩ, showing extremely low conduction loss. K4078-ZK-VB also supports drain current (ID) up to 85A and uses advanced trench technology to ensure its high efficiency and stability in switching applications.
