Working Principle

The S5JHE3_A/I Single-phase bridge rectifier works by using the four diodes in the bridge circuit to allow current to flow in only one direction. The diodes have a 0.5 V forward drop that covers the positive and negative half cycles of the input cycle. The reversed current at the negative half cycles is blocked by the diode, and the current can only flow in one direction. The output voltage will have a smoother waveform than the input. The bridge rectifier can be used to convert an alternating current to a direct current, helping reduce harmonic distortion and make the current more efficient.

The two pins of the rectifier are connected to the AC source, and the remaining two pins are connected to the load. When a voltage is applied to the rectifier, the voltage is converted from an alternating current to a direct current. Since the voltage has been changed from alternating current to direct current, the current can be used directly by the load, resulting in a more efficiently current.

The reduced forward voltage drops result in higher efficiency for the device, allowing for lower operating temperatures and increased system reliability. The ultralow reverse leakage current reduces the power losses and ensures higher circuit reliability.
