K2957 datasheet



This is 30V, 50A, Silicon N Channel MOSFET.

In an N-channel MOSFET, the source and drain terminals are connected to an N-type semiconductor material, while the gate terminal is insulated from the channel by a thin oxide layer. When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals.

N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.
