IRFI614GPBF Application Field and Working Principle

IRFI614GPBF is a 600V N-Channel MOSFET transistor manufactured by Infineon Technologies, with current ratings up to 25A at 25°C and up to 4A at 150°C. The device is characterized by low on-state resistance, high-frequency capability and excellent thermal performance. IRFI614GPBF has an integrated electro-static discharge protection which eliminates the need for extra external circuitry, and it is certified to withstand high-humidity environments and extreme temperatures.

The IRFI614GPBF is mainly used in high-power switching applications, such as in electrical power equipment, automotive electronics and consumer applications. It offers superior reliability and safety compared to conventional transistors, as it can withstand higher voltages and current ratings. It is typically used in DC-DC converters, motor switching and amplifiers, as well as in automotive power train applications.

Working Principle

The IRFI614GPBF is an N-channel MOSFET, which means the channel between the drain and source is an N-type semiconductor material. When a voltage is applied to the gate, it causes a conductive layer of electrons to form, allowing current to flow from the drain to the source. When the applied voltage is removed, the electrons are depleted, preventing current from flowing.

The IRFI614GPBF is also capable of operating at high-frequencies, meaning it can switch from "on" to "off" in a fraction of a millisecond. This is a great advantage in switching applications, as it can reduce switching losses and improve overall efficiency. It also offers protection against over-current and over-voltage, as it can quickly shut down when the conditions become dangerous.

In addition, the IRFI614GPBF has an integrated electro-static discharge (ESD) protection, which prevents it from being damaged by static electricity. This feature is especially important in consumer electronics and automotive applications, where there is an increased risk of exposure to ESD.
