Have an old PC switching power supply with a component labeled DA1 in its circuit board. Can anyone tell me what it is? It looks like a glass enclosed, small signal diode but with only a black band around its middle, not at one end such as a diode would have. I assume it's not a diode as elsewhere on the board there are other components I see as diodes which have a marking band around only one end, they are labeled D1, D2, D3, etc., and the board markings indicate which way these parts should be oriented on the board. The markings for DA1 do not indicate any such orientation, as would be necessary if it were some kind of diode. Might anyone know what this part is? The switching supply seems to work only every umpteenth time power is applied to it, and the DA1 component's location in the circuit appears related to the main switching circuit's initial starting drive for before the main regulation pulse width feedback loop gets going. Identifying its function seems important.
And got the following answer:
