Question

What are the recommend values for the resistornetwork in a isolated ACST435 application?

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 for a photo-TRIAC with 1A surge current.

Could you please give me the recommended values for this TRIAC combination?

Thank you in advance

Albert
