Only if datasheef want a small explosion! Choose a triac to match your line voltage and the required current. Sign up or log in Sign up using Google. SSRs come in two flavours – zero-cross and non zero-cross.


I will also need zero cross optoisolator to detect zero crossing on VAC, is that true?

Your controller circuit will need to detect the zero-crossing point and trigger the triac after the required delay. The V rating is absolute maximum V DC. Should I just connect drain and source to the AC wire?

Nice answer, but But still unclear. I don’t want to use relay because I need dimming Dimming by phase control.

Because I wana create one Why not buy a dimmer switch?

Consider developing your system using a low voltage transformer supply 12 to 50 V AC where a short circuit with your probes or hands won’t be lethal.

Use good wiring practices. You use a solid-state relay using a triac internally. For your dimming application you need non zero-cross so that you can switch on at any point in the cycle. Keep these very separate from your low-voltage circuits.
