[NTLK] Recurring failure on eMate300s

[Sylvain Pilet]

Thank you, Frank,

This seems to be the right reference, in any case it corresponds well to what I was expecting and to the power of an eMate. 
I hope until there is no further damage. I'll see if I can get some 1SMB5924BT3.
Just before your answer, we were, with another member of the list, able to identify a component that also seems to be compatible, it is the reference SMBJ9.0A. 

Yes, like you, I thought that it came from a bad power supply. It's a pity that the voltage and power is not noted (in silkscreen printing for example) near the connector. It would certainly have saved the life of many eMate!
