MT03-004 EDA Library
You should make it yourself. It's 5 pins in a circle, and the schematic is 4 diodes. 

For the footprint, set the grid using 'Q' to inch, then 'G' and set grid to 0.1" and lay down the 4 anode pins, making sure the pin numbers match the datasheet drawing. Then place the 5th pin at by editing the position to 70.71/70.71 mils. Take care in that the datasheet shows the bottom view, looking up at the part, rather than looking down through the part, as almost all do these days. Save in your library with a descriptive name for the component.

For the schematic symbol copy the diodes from a single diode library entry (eg. 1N4148) into a new component. Make sure the pin numbers match the datasheet.Add the footprint (and any other information you wish to add, but at least the comment and a default designator such as 'PD?').
