ALPHA & OMEGA SEMICONDUCTOR AOZ7271DV 600 V "Zero Bridge Loss" AlphaZBLTM Ideal Diode General Description The AOZ7271 is a 600 V AlphaZBLTM product that uses an internal 125 mΩ N-channel MOSFET to replace a diode when used in AC/DC diode-bridge application. The AOZ7271 reduces power consumption and heat dissipation. The diode bridge rectifier is a classic circuit used for fullwave AC-to-DC rectification and DC polarity correction. The high forward voltage of high voltage diodes causes high power loss and poses a thermal challenge. The AOS AlphaZBL product uses a controller and a 600 V MOSFET to enable ideal diode operation and can be used to replace the diode.
