WebMay 22, 2024 · One of the more useful BJT device plots is the family of collector curves. This is a series of plots of collector current, IC, versus collector-emitter voltage, VCE, at varying levels of base current, IB. To generate these curves we drive the base terminal with a fixed current source establishing IB. WebThere are two junctions in a BJT, the collector-base and the base-emitter. The collector-base junction, is able to withstand high voltage due to the very low doping of the drift layer of...
