I have only rudimentary knowledge of circuit design and need some advice.
I have a printed circuit board used in a device for automotive applications. I would like to include the means to prevent reverse current flow through a resistor on the board. Here is a section of the schematic ...
The advice I am seeking is what should the value of the diode be. In my case in an automotive application, when the engine is running the voltage could be 14 volts DC or so and the anticipated current could be as high as 1.0 ampere. I have seen articles stating there are different types of diodes for similar applications (junction diode, Schottky diode, etc.). I do not know which kind of diode would be preferred in this application nor do I know how to correctly specify the value for the diode. Any help is appreciated.
