Product Introduction
KIA2305-VB is a high-performance single P-channel MOSFET in a SOT23-3 package. It is small and compact, and is very suitable for designs with strict space requirements. The device has a drain-source voltage (VDS) of -20V and a gate voltage (VGS) of ±12V, which can provide stable switching functions in low-voltage environments. Its turn-on threshold voltage (Vth) is -0.8V, and it has a variety of on-resistance (RDS(ON)) options, providing 80mΩ, 65mΩ and 60mΩ on-resistance at VGS=2.5V, 4.5V and 10V, respectively, to ensure high efficiency under different gate drive conditions. The maximum drain current (ID) is -4A, and it uses advanced trench technology to optimize the conduction performance and current handling capability. It is widely used in portable devices, low-voltage switches and load switch circuits.
