SMD Marking - HELP PLEASE LOOK AT PICTURE - LE Z019

[jstarr]

I have googled extensively without success.  I am repairing a remote motor 12vdc controller that developed a short.   It is a PIC microprocessor controlled MOSFET switching controller.  It is made in Europe and has PCB designations that I think I understand.

There is a two lead component looking like a big black diode and the PCB symbol says DZ1 and DZ2 so I figure these are zeners.  I think the symbol is for ST and the marking says LE Z019. 

any help in id'ing this would be greatly appreciated.
