Really appreciate the help guys, I learned a lot on this experience. Thank you very much..
as of now we already highlighted it to the customer and they are looking into it.
does voltage ramping a cause for shorted diode?.. this is 220V requirement. See ramping of voltage.. is inrush voltage affects functionality of the schottky diode?https://files.engineering.com/getfile.aspx?folder=6d79abc8-084f-405e-aa78-db59b0950b42&file=voltage_sequence.JPG
We cannot change the design of the Board as this is customer owned Burn In Board, previously the part number of diode used was MBR20H150CTG which has 150V Peak Repetitive Reverse Voltage and in series to sustain the 220V, They upgraded it to TST20H300CW with Repetitive peak reverse voltage of...
See attached actual schematics of protection circuit of the burn in board. This is the part number of the diode TST20H300CW. The voltage for these supply is 220V and the current is 0.26A. The temperature is 125C and run for...

Hi to All,
This is my first time on these forums, i just like to ask if what maybe the cause of Schottky diode being shorted, We are using this schottky diode for protection circuit on our Burn In Boards, This is where the IC's are being loaded prior testing to BI (Burn In). We...
