Working Principles

The DST1045S-A is a single-phase and three-phase rectifier. It is a three-terminal device that uses an internal MOSFET. This diode serves two main purposes: rectifying alternating current (AC) to direct current (DC) and providing a stable voltage to a power supply.The electrodes of the diode are connected to the source, the drain, and the gate. When a voltage is applied to the source and drain terminals, the gate voltage is varied by varying the current between those two terminals. By controlling the gate voltage, the diode can either block or allow the current to pass through, thus controlling the current between the source and drain terminals.To rectify AC, the DST1045S-A acts as a high frequency “turn on” switch. The diode is connected to the source AC voltage so that when the voltage at the source is higher than the voltage at the drain, the current is allowed to pass through the diode. At this point, the current will be rectified and will flow only in a single direction.In order to provide a steady voltage source, the diode is connected between the source and the load. The diode will act as a voltage regulator by enabling a stable voltage source to be delivered to the load. The voltage will be regulated by adjusting the current between the source and the gate.
