NTE5457
Silicon Controlled Rectifier (SCR) 4A, 400V Sensitive Gate TO-202

See also >>> NTE5452 thru NTE5458

Description:
The NTE5452 through NTE5458 are sensitive gate 4 Amp SCR´s in a TO202 type package designed to be driven directly with IC and MOS devices. These reverse-blocking triode thyristors may be switched from off-state to conduction by a current pulse applied to the gate terminal. They are designed for control applications in lighting, heating, cooling, and static switching relays.
