The STP2NK90Z is one of the latest generation of power MOSFETs manufactured by STMicroelectronics. It is a high-voltage, low-ohm, N-Channel MOSFET which provides high current capability in an efficient package.

Unipolar MOSFETs, such as the STP2NK90Z, are widely used in applications where large currents need to be controlled with an electric signal. It is widely used in appliances, power converters, auxiliary power supplies, renewable energy converters, and motor control.

Application Field

The STP2NK90Z is mainly used in the design of power switching circuits which are employed in motor control applications. It can also be used in solar inverters, LED drivers, flyback switching power converters, and other applications with similar characteristics.

In motor control applications, the MOSFET can be used to control the power output of a motor. This allows for a wide range of motor speeds and other motor characteristics to be adjusted to the specific application.

In power converter applications, the MOSFET can be used to convert and regulate the voltage and current output. This allows the voltage and current to be adjusted and produces a stable output for efficiency and reliability.

The STP2NK90Z is also used in LED lighting applications due to its high-power switching capability. It allows for efficient lighting systems to be designed which are able to maximize light output.

The STP2NK90Z is ideal for high-power switching applications due to its low gate-source capacitance, high maximum voltage, and low gate-to-drain charge. These features make it an excellent choice for switching circuits with high current capabilities.

Working Principle

The STP2NK90Z is a N-Channel MOSFET which means it is composed of an N-type channel on its body. The N-type channel acts as an insulator, meaning no current can flow through it until the adequate electrical voltage is applied. This voltage is usually referred to as a gate voltage.

When the gate voltage is applied, the N-channel opens and current is able to flow through the MOSFET between the drain and source pins. The voltage and current flowing through the MOSFET can be adjusted by the gate voltage allowing it to act as a switch or an adjustable current or voltage regulator.

The gate voltage can also be used to control the speed of a motor. The motor speed can be adjusted by increasing or decreasing the gate voltage. This makes the STP2NK90Z a very useful component in motor control applications.

The various parameters of the MOSFET can also be adjusted by varying the gate voltage. This includes the on-resistance, turn-on/turn-off delays, drain current, and drain-to-source voltage. These adjustable features make the STP2NK90Z an ideal choice for power switching applications.

Conclusion

The STP2NK90Z is a high-voltage, low-ohm, N-Channel power MOSFET which provides high current capability in an efficient package. It is used in motor control applications, power converters, LED drivers, and other applications which require power switching capabilities.

The MOSFET can be adjusted by applying the required gate voltage which allows it to act as a switch, voltage regulator, or current regulator. This makes the STP2NK90Z ideal for producing efficient and reliable outputs in various applications.
