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 hermeti-
cally 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 con-
duction 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.
