Product introduction:
Product Introduction (SDM4952-VB MOSFET)
SDM4952-VB is a dual P-type + P-type channel MOSFET in SOP8 package, designed for low voltage, high efficiency applications. Its maximum drain-source voltage (VDS) is -20V, which is suitable for power management and switching circuits that require reverse control in low voltage applications. The on-resistance (RDS(ON)) of this MOSFET is very low, at 16mΩ (at VGS=10V) and 18mΩ (at VGS=4.5V), which can effectively reduce switching losses and improve energy efficiency. The maximum drain current (ID) is -8.9A, which is suitable for circuits with medium current requirements. SDM4952-VB uses Trench technology, which improves working efficiency and thermal stability of the system while maintaining low on-resistance. This MOSFET is widely used in power management, load switching, load control and protection circuits.
