About this product
The NEC 3P4M is a silicon-controlled rectifier (SCR, a type of thyristor) in a TO-202AA package, rated for 400V and 3A. It is used for gate-controlled power switching: a short gate pulse turns it on, and it stays conducting until the current drops below its holding level.

What is the 3P4M mainly used for?
It switches a load on with a short pulse on the gate. Once on, it stays conducting until the current falls below the holding level, so the gate alone cannot turn it off.
Does it conduct in both directions?
No. An SCR conducts in one direction only (anode to cathode). For AC control in both half-cycles, use a TRIAC or two SCRs connected in inverse parallel.
