Darlington Pair Explained The Darlington Pair as a Switch

WebTransistors have three terminals: the gate, the drain, and the source (on a bipolar transistor, the wires can be called the emitter, the collector, and the base). When the source (or emitter) is connected to the negative terminal of the battery, and the drain (or collector) to the positive terminal, no electricity will flow in the circuit (if you have only a … WebThe current gain equation of a typical transistor is: IE = ßxIB (collector current is equal to beta times the base current). The image shows a Darlington transistor with its pin configuration and its internal structure. We know that: On the first transistor: IE1 = ß1 x IB1. Equation (1). On the second transistor is: IE2 = ß2 x IB2. Equation ...

WebFigure 10. Example 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.
