ABSTRACT:
This relates to an optically isolated switching device made by coupling the output of a light emitting diode into a thyristor. Sensitivity is determined by optical flux density rather than total flux. Improved sensitivity is obtained with a mesa construction of a diode mounted on and bonded to a thyristor at a window in its cathode via a glass preform having a high refractive index.
