NTE NTE5408 Silicon controlled rectifier (scr) 3 amp sensitive gate Datasheet

NTE5408 thru NTE5410
Silicon Controlled Rectifier (SCR)
3 Amp Sensitive Gate
Description:
The NTE5408 through NTE5410 sensitive gate SCRs are designed to be driven directly with IC and
MOS devices. These SCRs feature proprietary, void–free glass–passivated chips and are hermetically sealed in TO5 type packages. These 4A devices are available in voltages up to 600V and with
a gate current of 200µA.
These NTE SCRs are reverse–blocking triode thyristors and may be switched from off–state to conduction by a current pulse applied to the gate terminal. The NTE5408 through NTE5410 are designed
for control applications in lighting, heating, cooling, and static switching relays.
