BUK9225-55A,118

The BUK9225-55A,118 is a high-voltage N-channel metal-oxide-semiconductor field-effect transistor (MOSFET). It is a single, in-line component, intended for use in general-purpose switching linear and for high-power, high-voltage applications. This component features high blocking voltage capability, an integrated gate protection, a wide safe operating area, and an ultra-low on-resistance. It can be used to switch power loads and is suitable for high-voltage, high-frequency circuits, such as motor drives, DC/DC converters, dc-ac inverters, and lighting control. In addition, the BUK9225-55A,118 is also suited for automotive, industrial, and home appliance applications.

A MOSFET works by controlling the flow of electrons between two terminals, the source and the drain, using a gate to regulate the current. When a voltage is applied to the gate, it creates an electric field that attracts – or pulls – electrons from the source to the drain, thus creating an electrical current. This is known as the "enhancement" mode. When no voltage is applied to the gate, the electric field is absent and the current is blocked, known as the "depletion" mode. As the BUK9225-55A,118 is an N-channel MOSFET, it operates in the "enhancement" mode. As such, it provides high levels of continuous current, while providing low levels of on-resistance as well as low current leakage.

The BUK9225-55A,118 features a typical rDS(on) (drain-source-on-resistance) of 55mΩ, a breakdown voltage of 800V, and a gate voltage of 20V. It is rated to deliver up to 1.1A of continuous current and has a maximum operating temperature limit of 175°C. It has an integrated gate-protection circuit, which protects against gate strike, sustaining voltage, over-voltage, over-current and transient pulses. Finally, the component is also RoHS compliant.

In conclusion, the BUK9225-55A,118 is a versatile, single-MOSFET component, suitable for a range of applications that require high-voltage, high-frequency circuitry. It has low on-resistance, high current limits, and an integrated gate protection circuit. This component is ideal for motor drives, DC/DC converters, dc-ac inverters, lighting control, automotive applications, industrial and home appliances.
