Hello!

The damage was caused by a failure (short circuit) of one of the tantalum capacitors.

First of all I'm looking for a datasheet for the DC/DC converter module Fortec 24-5/2W in the second picture.
It's probably 24Vdc to 5Vdc/2W converter, but i'm mainly interested in the pinout. It has 12 pins, some of them are connected together.

I managed to found a datasheet of some related DC/DC converter module with the same pinout:

Datasheet at the attachment. The DC/DC converter module is still working.

Now I'm looking for a datasheet for the diodes marked in the picture. They are in the SMA (DO-214AC) package. One of the diodes is still working - measurements show that it's a Schottky diode.
