Does anybody have a recent problem regarding to THT Zener Diode (especially 9V1 and 5V6) (They behave like short circuits)
Actually we faced with such a problem where we use 1.3W Zener diodes below their electrical ratings in our capacitive supplies (In our boards our worst case Zener condition is 600mW ).
We observe this problem in the first function test during manufacturing or in the life test also so the failure rate doesn’t depend on the working period of the electronic board.
I do appreciated for all kinds of comments.
Best regards,
Ahmet
