I decided to make a hot swap plate up using Two 12 v batteries. Using Two Vishay vs-90sq040
Schottky diodes Ord together.
The circuit works fine with the two batteries connected. But the problem is with one battery disconnected, I can measure full battery volts across the other diode which is meant to be blocking, I thought that diodes should block volts going across the diode in the reverse direction?
When I put a low value resistor across the battery adaptor + and - terminals, the volts on that diode dissapears.
The reverse leakage for this diode is 1.75ma.
Any ideas?
