The NTE5452 through NTE5458 are sensitive gate, 4-amp silicon-controlled rectifiers in TO202 type packages which are 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.
