Oa79 diode characteristics

The electrical characteristics shown by the Oa79 germanium diode are very much different from silicon diodes because the Oa79 diode has a voltage drop at 0.3v on the circuits.

And the leakage current of the Oa79 diode is larger than the silicon diode at reverse biased conditions.
