NTE5461 thru NTE5468
Silicon Controlled Rectifier (SCR)
10 Amp
Description:
The NTE5461 through NTE5468 series silicon controlled rectifiers are designed primarily for half–
wave AC control applications such as motor controls, heating controls, and power supplies; or wher-
ever half–wave silicon gate–controlled, solid–state devices are needed. These devices are supplied
in a TO220 type package.
