The IRFI520GPBF is a power field effect transistor that uses MOS technology to provide high power and high efficiency operation over a wide range of input voltage. It is a single low-level gate type high voltage, high side switch that can handle a maximum of 80 volts DC. It has a drain current rating of 20 amps and a drain source voltage rating of 500 volts. The IRFI520GPBF is designed for use in high side switching applications with a wide range of operating conditions; its particular application field makes it an ideal choice for applications like lighting, security and automotive markets. In this article, we discuss the working principle and application field of the IRFI520GPBF.

Working Principle

The IRFI520GPBF employs a three-terminal MOSFET (Metal Oxide Semiconductor Field Effect Transistor) with a gate terminal, source and drain terminals. The drain and source terminals allow current to flow, while the gate terminal is used to control the amount of current that can be passed. When a positive voltage is applied to the gate terminal, the drain-source channel increases its current carrying capacity and allows current to flow through the device. This is known as enhancement mode operation. When a negative voltage is applied to the gate terminal, it reduces the current carrying capacity of the drain-source channel, restricting the current flowing through the device. This is known as depletion mode operation. The IRFI520GPBF has an internal drain-source resistor that allows it to switch between enhancement and depletion mode very quickly.

Application Field

The IRFI520GPBF is designed for use in high side switching applications with a wide range of operating conditions. It can handle a maximum of 80 volts DC and is best suited for lighting, security and automotive market applications. It is also commonly used in motor control and power supply designs. In motor control applications, it can be used to control the current being delivered to the motor. This ensures that the motor does not exceed its maximum current rating, which can cause damage or failure. In power supply applications, the IRFI520GPBF can be used as an output switch to control the output voltage and current levels. It can also be used as an input switch to control the input current levels.
