WebThis diode has the performance of passing current (ON) when voltage is applied in the forward direction and stopping (OFF) current when the voltage is applied in the reverse direction. Compared with other diodes , the reverse recovery time (trr) is short, that is, the time that the switching diode takes from the on-state to the fully off-state ... WebA diode is an electrical device allowing current to move through it in one direction with far greater ease than in the other. The most common kind of diode in modern circuit design is the semiconductor diode, although other diode technologies exist. Semiconductor diodes are symbolized in schematic diagrams such as the figure below.
