I am very new on this site and new to electronics. I need to ask for your help in identifying an SMD component. This is what it says on it. 0C ш Please help if you can. It's 0C and what looks like a capital E lying flat on its back. It is in a back light for my car. A Mercedes Benz ML550

It is the MM3Z5V6T1G - a 5.6V Zener diode from OnSemi in SOD-323 package.
From the datasheet we can see the following marking scheme:
Note the date code location - placed at 90 degrees as you see in yours.
Also note that yours does have the Pb-free microdot in the bottom location (both are possible).
We can also decode the exact part number from the table in the datasheet:
The 0C indicates it is the 5.6V version.
The package also matches the lead style in your photograph.
