GBPC3504-E4/51 Bridge Rectifier, 35A 400V, 4-Pin GBPC. The Bridge Rectifier converts an Alternating Current (AC) input into a Direct Current (DC) output for full-wave rectification applications. The diode arrangement provides the same polarity of output for either polarity of input. A three-phase full-wave rectifier is an arrangement of six diodes in a bridge circuit configuration.
