General Considerations
Diodes have many characteristics that have to be accounted for. Some examples include the "turn on" voltage, referred to as forward voltage or voltage drop; maximum forward current, capacitance, leakage current, and reverse recovery time. Generally, diodes should never be exposed to large enough reverse voltages that can cause a reverse breakdown. The only exception is the zener diode [2].
How to Read Diode Datasheets
Depending on the application of the diode, datasheets will vary slightly.
