It is shown that after the device becomes thermally unstable the device may restabilize in a hot spot mode of operation. The IC, VCE thermal instability locus can accurately be predicted assuming the current density is uniform prior to hot spot formation. A new model is proposed which explains why the device may restabilize in a hot spot mode and why devices exhibit \"thermal hysteresis\". It is also shown using thermal mapping techniques that emitter current crowding exists in the stable hot spot mode. Finally, the experiments support the idea that second breakdown occurs when the current density within the hot spot reaches a critical value.","PeriodicalId":208049,"journal":{"name":"1970 IEEE Power Electronics Specialists Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126653503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The same materials were scanned ultrasonically by utilizing the s ingle transducer, throughtransmission technique with reflector plate, and recording variations in ultrasonic energy transmitted through the board thickness. A direct relationship was observed between ultrasonic transmission level and corona inception voltage.
