What's less obvious is that the four layers work like two transistors (an n-p-n and a p-n-p) that are connected together so the output from one forms the input to the other. The gate serves as a kind of "starter motor" to activate them. A thyristor is also like two transistors connected together, so the ... log in to twitter 登录推特
