    Hi All,
    I've bought 4 Solid state relays for switching on seperate contactors and now realise they're very large and probably overkill for switching 24 vac. I googled and found a triac array STA221A which is a lot smaller and seems perfect for my needs, however it seems to be discontinued and I can't find it in the UK, can anyone suggest an alternative. I know I could just use 4 triacs but that's going to make my pcb messier than it needs to be, surely there's an alternative?

    regards
    Germaine

    I'm switching some contactors that are only drawing a few milliamps (not sure of the exact figure but proba nothing more than 60ma max). I'll have a look at your suggested product above, thank you.
