    What are these mystery damaged SMD components?

    In another thread, I asked for help to identify another component from the same damaged PCB.

    I am asking for help to identify what the two damaged components above the op-amp could be.

    There are no markings visible on the components as that's the part of both components that is missing. The top one seems to have a white stripe on one side. The bottom one has feint markings of a white stripe which could of been burnt off when the component failed, or the marking was on the other end, which is now missing.

    Thanks for any help given.

    They could be rectifiers, but they look more like tantalum capacitors. Tantalum caps don't like over or reversed voltages.

    Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

          then the parts could be transient suppressor diodes (transorbs)
