• Battery chargers.
• DC-DC converters.
• Automotive systems.
• Industrial control systems.

Working Principle of FR3KTR

FR3KTR single diodes-rectifiers operate on the same principle as all other diodes, however, the main difference is their ability to tolerate higher temperatures, up to 175°C Tvj. The diode consists of a semiconductor material, usually silicon, in which a layer of oppositely charged material, usually metals such as aluminum or phosphorous, is incorporated. When a positive voltage is applied to the diode, the positive charges in the semiconductor material push the electrons away and thus creating an electric current.

When a negative voltage is applied to the same diode, the negative charges in the semiconductor material push the electrons away and thus creating a reverse current. This is why the FR3KTR devices are referred to as diodes-rectifiers-single, because they do both; they convert AC power into DC power and they are also able to regulate voltages. The high temperature operating junction of the FR3KTR makes them suitable for a variety of applications where temperatures may exceed the normal operating temperatures of traditional diodes.

Conclusion

The FR3KTR single diodes-rectifiers are automotive-qualified, large area, high power, and fast recovery devices that are suitable for a wide variety of applications in the automotive, computer, and industrial fields. They have a high temperature operating junction which is up to 175°C Tj, and extremely low reverse leakage current, making them a reliable and powerful choice for many applications. The working principle of the FR3KTR is the same as any other diode, however, they are equipped with special features that set them apart from traditional diodes and make them an ideal choice for many applications.
