The FR40G05 is a diode rectifier belonging to the single type which is most commonly used in AC/DC rectification. It belongs to the IGBT technology and has been developed for use in small applications such as TV, audio and similar small-scale applications.

The FR40G05 has the capability of rectifying a positive and a negative input AC voltage with a maximum current rating of 40mA. The diode is able to withstand currents up to 40mA, but should be avoided if values higher than 40mA are expected. Apart from AC/DC rectification, the FR40G05 may also be used to protect sensitive components from overvoltage.

Application field

The FR40G05 is mainly used for AC/DC rectification in small scale electronic equipments and circuits, including, but not limited to, consumer electronics such as TV, audio, and many other small-scale applications that require simple rectification or protection from overvoltage. Additionally the diode may be suitable for panel displays, light-emitting diode (LED) display systems, switching and control circuits and motor controls.

Working principle

The FR40G05 is a single type diode rectifier that contains three fundamental components; a P-N junction diode, a body diode and a reverse voltage blocking capacitor. The P-N junction diode and the body diode have the same polarity and can therefore be used for both forward and reverse current rectification. The P-N junction diode is responsible for the forward current rectification, controlling and reversed voltage blocking. The body diode is responsible for the reverse current rectification. The reverse voltage blocking capacitor is used for ensuring that the reverse voltage applied on the P-N junction and body diodes is kept within a certain maximum limit.

The working principle of the FR40G05 consists of rectifying both a positive and a negative input AC voltage with a maximum current rating of 40mA. When a positive voltage is applied on the diode, the body diode will conduct the current while the P-N junction blocks the reverse voltage as the reverse voltage blocking capacitor is taking the brunt of it. When a negative voltage is applied, the P-N junction will conduct the current while the body diode is blocking the reverse voltage.

In both cases, the reverse voltage blocking capacitor is taking the brunt of the voltage and thus protecting the P-N junction and body diodes from excessive voltage. This, in turn, ensures that the circuit is protected from too much current and overvoltage. Additionally, the FR40G05 is able to withstand currents up to 40mA.

Conclusion

The FR40G05 is a single type diode rectifier developed for use in small applications such as TV, audio and similar small-scale applications. In addition to AC/DC rectification, the diode can also be used to protect sensitive components from overvoltage. It is mainly used for AC/DC rectification in small-scale electronic equipments and circuits, and may also be suitable for panel displays, LED display systems, switching and control circuits and motor controls. The working principle of the FR40G05 consists of rectifying both a positive and a negative input AC voltage with a maximum current rating of 40mA which is able to withstand currents up to 40mA as well.
