K1446 datasheet


The K1446 is 7A, 450V, N-Channel Silicon MOSFET.

An N-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) 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.

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.
