Hi, the AN5114 describes in a good manner the isolated controll of a TRIAC. In chapter 3.3.1 there are some equations for determining the resistornetwork. But it seems that this equations do not really work for a ACST435 with 35mA gate current and fo...

Yes, of course we have to add an optocoupler or optotriac, but are there special requirements for the optocoupler or for the connection of optocoupler to the ACST435?Is there an application note?Thank you in advance.Albert
