Hello, I'm repairing an old mini-PC Gigabyte Brix. I found a photocoupler wich seems dead. On the top of this SMD 6 pins component, there is wrote : 4N3R. I found 4N3 serie datasheet but I can't found what's mean « R » for find similar. Could you help me pls ?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Where to buy photocoupler 4N3R or similar please ?
Ha yes, you are right, it‘s this mosfet. I dont understood first what a photocoupler did on the board of this mini pc with Celeron and with a very small external 40W charger ? But I found AN4 photocoupler datasheet and pin 6 was unused and matched with the open line measured. Wrong way.
PJ4N3KDW is hard to find, I tryied to find equivalent onr. And I found 2N7002DW

with same pins, same internal schematic and could you help for these specs pls, it's equivalent ?
