5-Kilowatt, 1-Kilovolt, Laminated Sonar Transistor.
Abstract
Results of 25 design IIIA pressings are discussed. Various types of base-collector structures were used. Measurements on 14 completed transistors are described. A theoretical model of thermal instability, which shows the importance of base series resistance at higher voltages, is investigated. The process is being modified to achieve additional base ballasting which should result in improved second breakdown performance without impairing other device characteristics. Further work on preferential etching, demonstrating the advantages of this method over cavitroning, is described. A package design for paralleling up to six pellets is included. (Author)
