NTE5511 thru NTE5513
Silicon Controlled Rectifier (SCR)
5 Amp
Description:
The NTE5511 thru NTE5513 all–diffused, three junction, silicon controlled rectifiers (SCR’s) are in-
tended for use in power–control and power–switching applications. These devices are available in
a TO66 type package and have a blocking voltage capability of up to 600V and a forward current rating
of 5A (rms value) at a case temperature of +75°C.
