Hi, I need help identifying an SMD diode on a PCB. The marking is:

ST ???

BBL

Z107

 

where "ST" is the ST Microelectronics logo. The "???" is some symbols that resemble "e3 6" or possibly "e3 G". Any ideas? I checked ST's site but could not find the code.

The context in which the part plays can help id what it is? 

Do you have a schematic of the board?

Do you know what the board is, and what it does?

Have you traced the circuit, or put a scope on the part while running.... ie is a rectifier, zener, chopper, level shifter, ect......

In other words it helps to know what it does.

It helps to know that many SMT semiconductor manufacturers use 3 letter ID codes on the device body rather than the full part number. Jim, above, found a table, supposedly from ST, that uses that code. Other manufacturers my use the same code for other things. You have to know the mfr, and sometimes the package to decipher those codes.
