I have two identical 72pin memory SIMMS out of an HP
workstation. One is
damaged by having a single 3pin SMD component physically destroyed, with
only the leads remaining. The second is complete and functional. The
damaged component's reference designation is CR5, so I am thinking it is a
rectifier and not a transistor. The black plastic SOT-23 package is marked
with 5A followed by a K rotated 90deg counter-clockwise.
Any suggestions on how to identify the part? Is there a pointer somewhere
to how SMD components are marked?
K is the typical symbol for the cathode.
It might work very well without it if it was reverse bias protection.
But it might have been used as a constant voltage drop of Vf.
