DESCRIPTION:
The NTE308 and NTE310 series integrated thyristor/rectifiers are all-diffused power monolithic circuits that incorporate a silicon controlled rectifier and a silicon rectifier on a common pellet. The NTE308 series types are used as bipolar switches to control horizontal yoke current during the beam trace interval; the NTE310 series types are used as commutating switches to initiate trace-retrace switching.
