SI7308DN-VB is a single N-channel MOSFET in DFN8 (3x3) package with low on-resistance and good high-efficiency performance. Its drain-source voltage (VDS) is 60V and gate-source voltage (VGS) is ±20V, which is suitable for medium and low voltage power management, load switching and other high-efficiency switching applications. The gate threshold voltage (Vth) of this MOSFET is 2.5V, which means it can be enabled at a lower drive voltage, suitable for low power control. SI7308DN-VB has a very low on-resistance of 12mΩ at VGS=10V and 15mΩ at VGS=4.5V, providing extremely low conduction losses and high current carrying capacity, ID up to 45A. This MOSFET uses Trench technology to provide efficient current conduction performance at a lower drive voltage and reduce switching losses. It is widely used in power conversion, battery management and load switching.
