Dear goldfist
Thank you for your replay
It should work with 220v current .
I saw a 5000 watts dimmer on a machine and it used a triac bta25 70b and diac db3.
I need the circuit its very important and urgent.
Dear Dave
Thank you for your replay
I found out that the blue one is a Diac db3.
But there is no mark on the black diod .
How can i know that model without mark? Can it tested with a multimeter?
