APPLICATIONS INFORMATION
The following show some typical application examples for the ZXRE060. It is recommended to include the
compensation capacitor C2 to guarantee stability. C2 may range in value from 0.1µF to 10µF depending on the
application and the environment.
Both C1 and C2 should be as close to the ZXRE060 as possible and connected to it with the shortest possible
track. In the case of and, it means the opto-coupler will have to be carefully positioned to enable this.
