Description
The K2769 is 900V, 3.5A, N-Channel MOSFET(Metal Oxide Semiconductor Field Effect Transistor).
This is a type of field effect transistor (FET) that uses an N-type semiconductor material as the conducting channel to control the flow of current.
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.
