Hi All,

I'm working on adding a external power supply to a current battery powered
product. 
Space is very tight, so I am going for something simple. Two schottky diodes
In a wired 'OR' configuration (one on the battery +ve, one on the external
supply +ve).
 Am I going to have problems with the high reverse leakage current if the
unit is powered
from the external supply with the batteries connected? (diode in question is
a 1N5818)
 According to the spec sheet, reverse leakage current can vary from 1mA@25C
upto 100mA@100C.
The unit runs from a single 9V PP3.

Ideas? Thoughts Comments?

Thanks in advance

Wayne
