Understanding the 2SK2225-E MOSFET

MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor, which is what the 2SK2225-E is. This kind of transistor is used in a lot of electronic devices and circuits because it can switch and boost signals well.

The way it works

In an N-Channel MOSFET, the conduction channel is made of negative carriers, like electrons, moving between the drain and source regions. How much current flows through this channel depends on how much voltage is put on the gate point. The gate makes an electric field that pulls electrons to form the conductive channel, allowing current to flow between the drain and the source.

Why 1500V Drain to Source Voltage (Vdss) Is Important: In high voltage uses, the Drain to Source Voltage (Vdss) of 1500V is a very important parameter. It shows the highest voltage that the MOSFET can handle between its drain and source lines and still work. Because it can handle a lot of power and voltage, the 2SK2225-E can be used in places like power supplies, motor drives, and industrial tools where these are important.

Continuous Drain Current (Id), Drive Voltage, and On-Resistance (Rds On) Values

The 2SK2225-E is capable of handling a continuous drain current of 2A at 25°C. The maximum continuous current that the MOSFET can handle according to this standard without going over its thermal limits is shown.

Drive Voltage (Vgs)

For dependable switching and device management, the MOSFET needs a drive voltage of up to 15V.

The 2SK2225-E’s on-resistance (Rds On) is 12 Ohms with a drain current of 1A and a gate-source voltage of 15V. Rds On is a significant characteristic that controls how effectively a MOSFET conducts current when it is fully switched on. In power electronics applications, lower Rds On values lead to less power dissipation and better overall performance.

Engineers can evaluate the 2SK2225-E’s suitability for particular high-voltage applications and improve its performance in electronic circuits and systems by being aware of these essential parameters.
