Hey guys got a ipad pro 12.9 in for not charging , changed out tristar but i must have knocked off this dude so need to steal it from another board just need to know what to use and polarity , is it the diode with 3 dots one side and a line the other ?

All sorted , it was the diode with the 4 dots one side & line the other with the doted side going to Gnd . happy charging iPad once again thanks for letting me think out loud xD
