WebA lower base-resistor voltage drop reduces the base current, which results in less collector current because I c = β I b. Collector current and emitter current are related by I c = α I e with α ≈ 1, so the increase in emitter current with temperature is opposed, and the operating point is kept stable. WebTherefore, the collector-base voltage VCB, collector-emitter voltage VCE, and emitter-base voltage VEB ratings are specified for transistors. There are two types of breakdown voltages that determine the voltage ratings: those inherent to a transistor such as V (BR)CBO and V (BR)CEO and those dependent on the base circuit conditions such as … character couture packages disney world
