Hello I can't find a datasheet for the triac BTB12-600GM produced by ST. Which current triac replaces the old one? Where can I find a datasheet to figure it out myself? Thanks for your help! Thees

I have to repair a 15 year-old extractor hood and have to replace the triac. The triac is one of the components that controlls the speed of two fans inside the hood.
