WebExample Darlington Collector Current (I C) vs. Collector-Emitter Voltage (V CE) With a Darlington transistor, however, I C rises suddenly as V CE approaches 1V, as shown in the graph above. If you attempt to set V CE to less than 1V in the same way as with a single transistor, therefore, an output current might not be generated at all. WebThe base turns the transistor on. And then a much greater current flows from collector to emitter, but only if the collector has sufficient positive voltage.
