Product Introduction
The K2957S-VB is a high-performance single N-channel MOSFET in a TO263 package, designed for high current and low voltage applications. The device has a maximum drain-source voltage (VDS) of 30V and can withstand a maximum drain current (ID) of up to 70A, making it suitable for applications requiring strong current drive. The threshold voltage (Vth) of the K2957S-VB is 1.7V, ensuring effective conduction even at low gate-source voltages. In addition, the on-resistance (RDS(ON)) of the MOSFET is 8mΩ at 4.5V and drops to 6mΩ at 10V, which not only reduces power consumption but also reduces heat generation, helping to improve the overall efficiency of the circuit. The K2957S-VB performs well in applications such as power management, switching power supplies, and motor drives, and is widely used in a variety of electronic devices.
