    When I was cutting open my cell phone charger I cut into a component it looks like a transistor and has the following written on it 3015 HJ A1 I cant find any data on it and if it is in fact a transistor

    Could it be a MOSFT switching transistor

    The fuse is blown badly, from a massive AC input current, that shows the main switching FET is dead, and possibly some or all of the 4 bridge rect diodes on the input.

    That little part will be the main switching FET, usually they use a high voltage NFET about 800v rated. 2SJ and 2SK parts are FETs and sometimes they just show the number and leave those letters off.

    "2SK3015" is a real part but does not seem to match your device. Do you have a better photo?

    It was struck by lightning. a real problem here in Zimbabwe. I think its best I just build a new power supply or buy one because I dont know enough or understand this type of power supply.

    Thanks for your help
