Connecting method of composite triode
A composite transistor is two and more of a transistor collector connected together, and the first transistor emitter coupled directly to the base of second transistors, which are connected in turn, and finally leads to E, B, C three electrode. Also known as the Darlington tube, whose amplification is the product of both magnification. Generally used in power amplifier, voltage regulator circuit.
If it is like T1, E T2 B, C and C connection, at the same time into B, E, C.
main features(1) magnification is large (up to hundreds, thousands of times);(2) strong driving ability;(3) large power;(4) switching speed is fast;(5) can be a success rate amplification module;(6) easy integration.
