Product Introduction - SFT1431-VB MOSFET
The SFT1431-VB is a single N-channel power MOSFET in a TO251 package, designed for high-efficiency power switching applications. It has a drain-source voltage (VDS) of -30V and a gate-source voltage (VGS) of ±20V, suitable for a variety of low to medium voltage applications. The threshold voltage (Vth) of this MOSFET is 1.7V, which can work smoothly in most standard drive circuits. The SFT1431-VB has a very low on-resistance (RDS(ON)) of 7mΩ (VGS = 10V) and 9mΩ (VGS = 4.5V), which makes it have extremely low power loss and excellent efficiency in high current applications. Its maximum drain current can reach 50A, which is very suitable for applications with high current and high efficiency requirements such as power management, load switching, and motor drive.
