I have an Artesyn 7001138-Y000 835 server power supply unit that has a burnt component. The burnt component reads S4 6CA and has the general Semiconductor logo on it. I have been looking online to find the specifications so I can replace it, but I have been unsuccessful. If anyone can help me out so I can get this running again that would be awesome!

Smoked SMD diode with marking S4 6CA

    \$\begingroup\$ I think your problem is rather why it burnt. Diodes just don't burn unless something happen to them. \$\endgroup\$ – pipe Jun 27 '16 at 11:07
  • \$\begingroup\$ I got it from a flying buddy. He was converting it to use as a power supply for his lipo charger. He was trying to install a 1k resistor between pins 17 & 19 to boost the voltage and I reckon he shorted something. The burnt diode was the only damage I could find to the board. \$\endgroup\$ – Maarten Jun 29 '16 at 7:35
  • \$\begingroup\$ That S4 answer also helped me thanks, the S4 I found was a much smaller package and could not find the correct one so used a B260A -13-F Farnell 1843682 SMA package. \$\endgroup\$ – Dave williams Mar 23 '18 at 10:36

Vishay/General semiconductor SS14. It's a 40 volt schottky diode.

The other digits refer to line and date. See here: Vishay markings

  • \$\begingroup\$ Awesome!! I'd been looking for on the Vishay site but this datasheet had eluded me. \$\endgroup\$ – Maarten Jun 29 '16 at 7:38
  • \$\begingroup\$ @Maarten. Glad to help. Remember to mark it as answered when you feel that your original question has been just that. \$\endgroup\$ – winny Jun 29 '16 at 7:48
