Hey All,
While working on a 200ASC board, I managed to crack and break a small surface mount zener diode right next to the power terminal linking the 200ASC to a 200AC (see pics). Would anyone have any idea how to identify this component so I could replace it? It has no markings at all. Attempting contact with ICEPower or PartsExpress has not yet been helpful.
Thanks!

If you have another module with the part intact, you can get readings from the working board. You will need a voltmeter... Find the voltage across the diode and order one the same value in the same physical size.
It's ok to go up in power ratings ... you can replace a .1 watt with a .5 watt, so long as it fits... but don't go down.

So that voltage reading across the diode when the board is running will tell me the breakdown voltage of the diode?

If you contact B&O they will help you out with a value.
It looks like all other MELF diodes. Could be a 1N4148 or a zener.
