NTE5426 Silicon Controlled Rectifier (SCR) Sensitive Gate, TO220 Isolated Description: The NTE5426 is silicon controlled rectifier (SCR) in an isolated tab TO220 type package. This device may be switched from offstate to conduction by a current pulse applied to the gate terminal and is designed for control applications in lighting, heating, cooling, and static switching relays.
