SI7405DN-T1-GE3-VB MOSFET Product Introduction
SI7405DN-T1-GE3-VB is a high-performance single P-channel MOSFET in a DFN8 (3x3) package for low-voltage power management and high-efficiency switching applications. Its drain-source voltage (VDS) is -12V, gate-source voltage (VGS) is ±8V, and gate threshold voltage (Vth) is -0.8V, which can be enabled at a lower drive voltage, suitable for low-power and high-efficiency circuit design. SI7405DN-T1-GE3-VB has an extremely low on-resistance of 15mΩ at VGS = 4.5V and 21mΩ at VGS = 2.5V, which can effectively reduce power loss and provide efficient current transmission. The maximum drain current (ID) is -25A, making it suitable for handling medium current loads, and its deep trench technology reduces switching losses while improving current conduction efficiency. This MOSFET has a wide range of uses in battery management, load switching, power control and other applications.
