FR20B02 Application Field and Working Principle

The FR20B02 is a type of diode rectifier from General Semiconductor which is typically used in different applications.

Diodes are two-terminal conducting devices, usually made using semiconductor materials, which allow current to pass through in one direction and block it the other direction. Most commonly, diode types are distinguished by their power, PIV rating, peak repetitive reverse voltage (PRV), forward current rating (IF) and type of package. FR20B02 has a PRV of 20 Volts and IF of 2 Amps.

FR20B02 Application Fields

This type of diode rectifier is mainly used in the following application fields:

• Lighting Equipment: FR20B02 diode rectifiers can be used in lighting equipment such as halogen lamps, flashlights, ceiling lamps, etc. The high PIV rating of the diode rectifier helps in providing good voltage conversion to the lighting equipments.
• Medical Equipment: This type of diode rectifier is also used in medical equipment like CAT scanners, MRI scanners and other medical devices which require high voltage conversion.
• Industrial Equipment: They are commonly used in industrial equipment like robotic arms, welding machines, 3D printers and so on.
• Communication Equipment: The diode rectifier is also used in communication devices like cell phones, radios, modems and other communication related devices.
• Power Converters: FR20B02 diode rectifiers are widely used in power converters for the purpose of voltage conversion.

FR20B02 Working Principle

A diode rectifier works on the principle of rectifying an AC waveform, which results in an increased voltage with a longer duration. The process involves passing an AC waveform through a diode, which sets up a current carrying path for the chosen waveform with the help of a diode bridge, also known as a reverse voltage voltage transmission path. The diode will conduct the current on one side of the waveform and will not conduct the current on the other side this is because the diode has a property known as polarity.

When the AC waveform is sent through the rectifier, currents varied as per the waveforms. The rectified waveform is then stepped up to a higher voltage in a voltage regulator where it is regulated at a certain voltage. The voltage passed onwards to the load is then a pure DC voltage.

Conclusion

FR20B02 is a general purpose diode rectifier from General Semiconductor which is typically used in applications related to lighting, medical equipment, industrial equipments, communication equipment and power converters. The diode works on the principle of rectifying an AC waveform, which results in an increased voltage with a longer duration.
