LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 60134).

Note

1. If both diodes are in forward operation at the same moment, total device current is max. 110 mA. If one diode is in

reverse operation and the other is in forward operation at the same moment, total device current is max. 200 mA.
