The K4097 is 500V, 9.5A, 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.

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.


• Low ON-resistance, low input capacitance, ultrahigh-speed switching.

• Adoption of high reliability HVP process.

• Attachment workability is good by Mica-less package.

• Avalanche resistance guarantee.
