The question that then arises is to what extent the boundaries of the working region may be transgressed. For example, under what cir- cumstance is a 'conducting hard' point hke Figure permissible, where both the anode dissipation and the maximum cathode current are being exceeded ? Conducting hard. Cut-off Figure The answer is that the anode dissipation may be instantaneously exceeded, provided it is not exceeded on the average, the average bei

Cut-off Figure The answer is that the anode dissipation may be instantaneously exceeded, provided it is not exceeded on the average, the average being taken over a period short compared with the thermal time-constant of the anode structure. The maximum cathode current rating can apparently also be exceeded instantaneously provided it is observed on the average. What is happening.
