I was repairing an smps ATX power supply I found a damaged component that I could not it recognise. I thought it's a power switch since it was mounted to a heat sink along with tow D13007 NPN power transistors and I could not find the datasheet due to the missing part number after explosion .Can someone with expertise in this type of circuits guess what this could be?

  • \$\begingroup\$ It looks like maybe you meant to upload 2 pictures, but instead uploaded the same one twice? As it stands I don't think you've provided enough info to answer the question. What power supply model is this? And what do the traces on the back leading away from it look like? A clear picture of the area around the part would be helpful too. \$\endgroup\$ – Drew Mar 1 at 6:22
