The RB520G-30 RLG is a single-phase glass-passivated bridge rectifier with Surge Overload Ratings of 200 Amperes Peak (non-repetitive) and 50 Amperes RMS (Continuous). It is suitable for printed circuit board applications and is used as a rectifier diode in a variety of applications where load currents up to 30 Amperes are expected. The device is constructed with highly reliable and durable glass passivated chips and is intended for use in almost any rectifier applications such as DC power supplies, battery chargers, and low frequency inverters.

Application Field

The RB520G-30 RLG is applied in any type of rectified circuits, such as DC power supplies, battery chargers, and low frequency inverters. It features glass passivated chips for maximum reliability and superior ruggedness. RB520G-30 RLG is suitable for heavy-duty applications such as AC/DC mains power, UPS, automotive, and chargers. Its wide operating temperature range from – 55 °C to +150 °C and its high thermal fast recovery time allows it to be used in extreme temperature environments.

Working Principle

The RB520G-30 RLG works by allowing current to flow through the diode in one direction, while blocking current flow in the opposite direction. This is the basis of a rectified circuit where a single, alternating AC voltage is converted into a DC voltage. A bridge rectifier is composed of four individual diodes arranged in a symmetric pattern that allows current to flow in either direction through the diode and into the load. When compared with a traditional circuit, this arrangement allows for a much more efficient transfer of power from source to the load. The RB520G-30 RLG also features a high thermal and surge overload ratings. This means that it can easily handle applications where there is a rapid change in the load, without the need for additional surge protectors.

Conclusion

The RB520G-30 RLG is an ideal single-phase glass-passivated bridge rectifier for use in a wide range of applications. Its fast recovery time and high thermal and surge overload ratings make it a reliable choice for applications that require reliable rectified power. Its superior ruggedness also makes it suitable for extreme temperature environments. It is possible to use the RB520G-30 RLG in both AC to DC rectification and low frequency inversion applications due to its easily programmable and highly reliable nature.
