Determination of Requirements for Overvoltage and Overload Protection of Transistors
Abstract
Design requirements for transistor protective devices were determined. The exact nature of the protective devices is not to be determined as they may be either additional devices incorporated in the circuit, additional protective circuits, or the proper choice of the basic circuit parameters. Desired are discrete values of voltage, current, power, time constants, and any other necessary parameters that an equipment designer might readily use. The following recommendations are made as a result of the work performed: (1) more adequate transistor specifications are required, such as specifications which describe transistor operation at several temperatures rather than the present 25 C only; (2) transistor manufacturers should supply more thermal information about their products; (3) further work should be performed for the express purpose of designing the equipment necessary to determine accurately the thermal response of transistor junctions; and (4) further work should be performed for the express purpose of designing the equipment necessary for a more accurate transistor thermal analog.
