AOZ7270DI
600V "Zero Bridge Loss" AlphaZBLTM Ideal Diode General Description Features The AOZ7270 is a 600V AlphaZBLTM product that uses
an internal 190mΩ N-channel MOSFET to replace a
diode when used in AC/DC diode-bridge application. The
AOZ7270 reduces power consumption and improves
thermals.
The Schottky diode bridge rectifier is a classic circuit
used for full-wave ac-to-dc rectification and dc polarity
correction. The high VF of high voltage Schottky diodes
cause high power loss and pose a thermal challenge.
AOS' AlphaZBL product uses a controller + 600V
MOSFET to enable ideal diode operation and can be
used to replace the schottky diode. Replacing the 4
diodes in a full-wave bridge rectifier circuit with a low loss
MOSFET reduces power dissipation and results in
improved thermals and higher reliability operation. Replaces a power diode in HV bridge rectifier Self-powered in AC system Internal 0.19Ω 600V N-channel MOSFET Low reverse threshold 1mV Low quiescent current 5uA Thermally enhanced Applications AC/DC HV bridge rectifier The AOZ7270 is self-powered from the AC line without
the need of an extra voltage supply.
The AOZ7270 is available in a 5mm×7mm DFN-12L
package and is rated over a -40°C to +125°C ambient
temperature range. Typical Application
