Product introduction：
1. KIA3423-VB Product Introduction
KIA3423-VB is a high-performance single P-channel MOSFET designed in SOT23-3 package, optimized for low-voltage switching and driving applications. The maximum drain-source voltage (VDS) of this MOSFET is -20V, and the drain current (ID) reaches -4A, which is suitable for use in a variety of small electronic devices. Its gate-source voltage range is ±12V, and the enable threshold voltage (Vth) is -0.8V, ensuring that it can be turned on at a lower gate voltage. The on-resistance (RDS(ON)) of KIA3423-VB performs well at different gate voltages, which are 80mΩ@VGS=2.5V, 65mΩ@VGS=4.5V and 60mΩ@VGS=10V respectively. The use of advanced Trench technology makes this MOSFET have a wide range of application prospects in high-efficiency and miniaturized designs.
