Document Type and Number:
WIPO Patent Application WO/1983/002039
Kind Code:
A1
Abstract:
A photocoupler which is capable of operating with a high sensitivity, high speed, low voltage and low current. For that purpose, a photodetector (13, 20, 33), coupled through an insulator that can pass light with a light emitting element (11, 21, 31), is composed of an electrostatic induction transistor, a field effect transistor or an electrostatic induction thyristor.
