WebApr 5, 2024 · The TIP122 is an NPN Darlington pair transistor. This transistor simply works like a typical NPN-type transistor, but it includes a Darlington pair. So the first transistor’s emitter terminal is connected to the second transistor’s base terminal and also the collector terminals of two transistors are connected to make a Darlington pair. WebA self-oscillating mixer is disclosed, and includes two bipolar transistors coupled as a Darlington pair, where the base of the first transistor receives an input signal, and where the common collectors of the transistors generate an output signal; and a feedback resonator operable for coupling signals at the local-oscillator frequency from the ...
WebDec 28, 2015 · A darlington pair allows you to combine the best of both worlds. The first transistor is a normal high gain BJT, multiplying the Base-Emitter current and permitting a large multiple of that to flow from Collector to Emitter. The second transistor is a power BJT, which has a much lower gain, but better maximum currents.
