Introduction to R5020418FSWA

R5020418FSWA is a rectifier diode. It is a single-phase bridge rectifier with a peak reverse voltage of 400V and a maximum forward surge current of 18A. It also has an axial lead version and a surface-mount version. The forward voltage drop is 455 mV at 10A under normal conditions. R5020418FSWA is used for AC/DC power supplies, LED lighting, automotive, LTE cellular base station power supplies, and many other applications.

Features of R5020418FSWA

R5020418FSWA has a number of advantages compared to other rectification diodes. It has a low thermal resistance, low voltage drop, and low reverse leakage current. It also has a tolerance of ± 0.3 V, and can handle high forward surge currents of up to 18 A. In addition, it has a short recovery time, high reverse voltage protection, and low noise.

Application Field

R5020418FSWA is mainly used in AC/DC power supplies, LED lighting, automotive, and LTE cellular base station power supplies. In power supplies, it can be used as a full-wave rectifier, allowing AC current to be converted into DC current. In LED lighting, it is used to regulate the current and hence the intensity of the light. In automotive, it is used for controlling voltage in the charging system. Finally, in LTE cellular base station power supplies, it helps to protect the circuit from overloads.

Working Principle

R5020418FSWA works by allowing current to flow in one direction while blocking current in the opposite direction. When an AC voltage is applied to the diode, the anode will become slightly positive with respect to the cathode. This causes the diode to conduct in the forward direction and allows current to flow. However, when the polarity is reversed, the anode will become slightly negative with respect to the cathode, which causes the diode to block current and not conduct. This is how R5020418FSWA helps to convert AC into DC.

Conclusion

R5020418FSWA is a single-phase bridge rectifier with a number of advantages. It is mainly used in AC/DC power supplies, LED lighting, automotive, and LTE cellular base station power supplies. It works by allowing current to flow in one direction while blocking current in the opposite direction. With a low forward voltage drop and a high surge current capability, R5020418FSWA is a reliable choice for rectification and conversion applications.
