Low-voltage diac?

Neil Preston · 2004-12-30T03:35:27+00:00

Is there available a DIAC with breakover voltage ratings in the 5-15V range?Or an equivalent device?All I've seen so far are in the 50-60v range.I wish to make a sensitive triac trigger to detect certain fault conditionson an AC signal, and I need the negative resistance characteristics typicalof a diac, but at much lower threshhold voltage. It must also bebidirectional.Thanks,Neil

I was surfing the other day and came across some info on four-layer devices, and it sounds like this is what you're looking for. They are lower voltage than DIACs.
