The IXFK40N90P is a power Metal Oxide Semiconductor Field Effect Transistor (MOSFET) designed to be used in applications such as high-power switching, motor control, and general power management. This particular unit has a high current rating of 40A and an on-state resistance of 0.012Ω, with a drain-source voltage tolerance of 180V. In general, this MOSFET is designed to act as a switch, allowing current to flow from the source to the drain when a bias voltage is applied to the gate.

Application Field

The IXFK40N90P is designed for use in applications with a need for high-current switches operating at high voltages. Additionally, it is well-suited for use in power management applications and motor control circuits. Its low on-state resistance and high current rating make it ideal for use in a variety of power-intensive tasks. Additionally, this MOSFET has been tested to ensure its stability and reliability, even in extremely harsh conditions, making it a suitable choice for use in industrial and automotive applications.

Working Principle

The IXFK40N90P works by using the principles of Negative Temperature Coefficient (NTC) and Source-Drain Transport (SDT) to create an electronic switch. When a positive bias voltage is applied to the gate, it creates an electric field across the Gate-Source region, which causes an increase in current between the source and the drain. This causes the metal-oxide semiconductor to act as an electronic switch, allowing current to flow from the source to the drain. Additionally, the Gate-Source voltage must remain constant in order for the MOSFET to remain in its switched-on state.

Once switched on, the IXFK40N90P has a low on-state resistance, allowing for minimal losses in power. The drain-source voltage drops quickly as the device reaches the end of its continuous current rating, ensuring that it remains safe for use in high-voltage applications. Additionally, the low on-state resistance ensures that the device will not cause too much heat or other losses in power consumption.

When the bias voltage across the Gate-Source junction is removed, the MOSFET turns off, preventing current from flowing from the source to the drain. The device is designed to be switched off quickly, allowing it to be used in applications where current must be switched on and off rapidly. The IXFK40N90P features a high, reverse-blocking voltage, ensuring that it can be used safely in applications where high voltages are present.

Overall, the IXFK40N90P is an excellent choice for use in high-current switching and power management applications. Its high current rating, low on-state resistance, and high reverse-blocking voltage make it well-suited for use in a variety of applications. The device is designed to be stable and reliable, even in harsh conditions, making it a great choice for use in industrial and automotive applications.
