General Description

The AOZ7200CI is a 600V AlphaZBLTM product that controls

the external N-channel MOSFET to replace a diode when

used in AC/DC diode-bridge application. The AOZ7200CI

can help to reduce power consumption and heat dissipation.

In diode-bridge application, the AOZ7200CI senses the

voltage drop and reduces the forward conduction loss to

the minimum value. When the forward current is reversed,

the AOZ7200CI turns off the external switch and suffers the

reverse voltage. In AC/DC application, the AOZ7200CI is

self-powered system without extra voltage supply.

The AOZ7200CI is available in a SOT23-5 package and is

rated over a -40°C to +125°C ambient temperature range.
