Bridge Diodes
A bridge diode is a semiconductor component that combines rectifier diodes connected in a bridge arrangement in one housing and converts alternating current to direct current by full-wave rectification; single-phase types contain four diodes. It is used in power supplies, battery chargers and the supplies of brakes, contactors or valves with DC coils to obtain DC voltage from AC voltage. In this category, Konsan-branded 35 A 1000 V and 50 A 1000 V bridge diodes are sold by the piece. Choose the bridge diode by the forward current rating that covers the DC current drawn by the load, the reverse withstand voltage that exceeds the peak value of the input voltage, the terminal type and the possibility of mounting on a heatsink. The current on the label applies to the condition in which the housing is attached to a heatsink and held at a specific temperature; the current that can be carried drops when used without a heatsink. The output is pulsating DC, and a filter capacitor is added to the output for a smooth voltage. A bridge diode only rectifies; it cannot replace a transformer that converts the voltage level or a regulator that keeps the output constant.
