  • Abstract
    A developmental germanium power transistor is described. The collector heat dissipation is 20 watts at room temperature when the transistor is properly mounted. The unit delivers a peak collector current in the order of 1 ampere and has a peak collector voltage of 60 volts. Problems concerning heat transfer and mounting are discussed. Electrical characteristics for 75 degrees F. and 175 degrees F. mounting base temperature are given.
