PROTECTIVE TRIAC WITHOUT GAPETTE, REALIZED FROM A SUBSTRATE WITH HIGH RESISTIVITY

摘要

P THE INVENTION CONCERNS A PROTECTIVE TRIAC WITHOUT TRIGGERING, INJURING IN CASE OF OVERVOLTAGE. / P P TO AVOID UNCERTAINTY ON THE TENSION VOLTAGE AND A LACK OF UNIFORMITY OF STARTING CURRENTS, IT IS DETERMINED THAT THE TRIGGERING IS DETERMINED BY THE VOLUME CLASSIFICATION OF A GA1AS1 JUNCTION BETWEEN THE TRIGGER REGION INTERNEGA1 OF ONE OF THE THYRISTORS HEAD-BECHETH1, TH2 CONSTITUTING THE TRIAC AND A SPECIFIC REGIONAS1 MORE DOPED THAN THE CENTRALECE1, CE2 OF THE SUBSTRATE. SPECIFIC REGIONAS1 IS PROPERLY LOCALIZED BETWEEN THYRISTOR CATHODE SHORT CIRCUIT HOLES. / P
