A couple of questions:
How do you KNOW it is a diode? Was there a reference designator printed on the printed circuit board it came out of? Perhaps a CRxx or Dxx.
Is there a schematic symbol printed on the circuit board? Any polarity markings?
Have you tested the component? Diodes typically fail shorted followed by burning open from excess current. The component in the picture looks undamaged. Did you check it for continuity? Diode voltage drop in both directions? Resistance value?
How did you isolate the fault to that component?
Any idea of the function of that component in the circuit?
==========================================================
EDIT
Do the 9 caps sit across a communication data buss? The diodes and capacitors might be used for electronic interference noise suppression. Or voltage termination
