Working Principle

When using a S5A V6G rectifier diode with an AC input, the diode is operated in a pure rectification mode. The diode is placed in parallel with the input AC voltage source and the output DC voltage source. The diode will pass current in one direction and block current in the other direction. The forward voltage diode drop of the diode will establish a peak-to-peak voltage across the load. The output DC voltage value is determined by the peak-to-peak voltage and the load resistance. The current ripple across the load is minimized by the combination of the low forward voltage drop of the diode and the low resistance of the load.

When the positive half cycle of the input AC voltage is applied to the diode, the diode conducts and the voltage across the load will increase. The current flow through the diode is determined by the load resistance, the diode junction\'s forward voltage drop, and the input AC voltage magnitude. In the negative half cycle of the input AC voltage, the diode blocks the current flow and the voltage across the load will decrease. This process will repeat through each half cycle of the input AC voltage resulting in a DC voltage output across the load at each time interval.
