SFT1431-VB MOSFET Product Introduction
SFT1431-VB is a unipolar N-type MOSFET in TO252 package, designed for high-efficiency, high-current applications. Its drain-source voltage (Vds) is 30V, suitable for low to medium voltage power management, power conversion and motor drive. The device has a low threshold voltage (Vth) of 1.7V and can be turned on at a lower gate voltage, providing faster response time and efficient switching performance.
SFT1431-VB uses Trench technology and has extremely low on-resistance. At Vgs = 4.5V, the on-resistance (Rds(on)) is only 6mΩ, and at Vgs = 10V, the on-resistance is further reduced to 5mΩ. This enables the MOSFET to effectively reduce power loss and heat generation during operation, improving the overall efficiency of the system. The maximum drain current (Id) is 80A, which can meet the requirements of high-power loads and is suitable for high-current applications such as motor drives and high-efficiency power converters.
