Greetings all, and new to the forums.
I have been involved in a circuit design and research for the circuit. Our circuit uses a DIAC, with a breakover voltage of 35-40. Looks like the DIAC is slowly being phased out, as more and more, newer technology emerges in the lighting industry. DIACs were very commonly used to trigger TRIACs in light dimmers, however, with more lighting going towards LED and CFL's, looks like demand for the old world DIAC has died off, and manufacturers are not wanting to make these things. Read that as expensive and difficult to obtain.
I have found a few manufacturers, DIOTEC, STMICRO, and NTE that still make them. Only for who knows how much longer before they send out a obsolescence notice...
So that brings me to my question. What else can take the place of a DIAC... Are the manufacturers just including this part in with the TRIACs, or has the technology changed that much were there just isnt a viable solid replacement for this?
Thanks
