The 1N5819 is a Schottky Diode with forward voltage drop of 600mV and a forward current of 1A. Since it has a very low forward voltage drop it can be used in reverse polarity protection circuits, unlike a normal diode which has more than 1V as forward voltage drop 1N5819 only has 600mV drop across it when 1A current is flowing through it.

Compared to normal diodes Schottky diode also has relatively faster switching speeds and hence can be used in high frequency switching circuits. The reverse blocking voltage for 1N5819 is about 28V only which is kind of a downside for all Schottky diodes so make sure this does not affect the performance in your circuit.

The UF4007 from Multicomp are axial leaded ultra fast recovery power diode in DO-41 package. The device features glass passivated chip junction, low cost, fast efficient plastic rectifiers, high efficiency, low forward voltage and low leakage current and high surge current capability. 

UF4007 diode has a cathode (-) and anode (+). In the schematic symbol, the tip of the triangle with the line on top of it is the cathode. Diode polarity Current can flow from the anode to the cathode only and never from the cathode to the anode - UF4007 diode is like a one way valve.
