Product Introduction
K2977-VB is a high-efficiency single N-channel MOSFET designed with TO220F package, suitable for high current and low voltage applications. With a maximum drain-source voltage (VDS) of 30V and a maximum drain current (ID) of up to 68A, this device is very suitable for power management systems that require high power and high efficiency. The threshold voltage (Vth) of K2977-VB is 1.7V, and it can be turned on quickly at a lower gate-source voltage. Its on-resistance (RDS(ON)) is 2mΩ at 4.5V and drops to 1mΩ at 10V, which allows it to provide high current while greatly reducing power consumption and heat generation, thereby improving the performance and reliability of the overall system. K2977-VB is particularly suitable for motor control, switching power supplies and various high-power applications, and has become an indispensable component in modern electronic devices.
