TIP41C Circuit

The TIP41C is an NPN-type transistor used primarily as a switch or to amplify signals. It is commonly used in audio amplifiers, power supplies and motor control circuits.

This circuit diagram describes a loudspeaker, in short, an input signal amplified by several transistors and output to realize the function of the loudspeaker we use every day. The focus of the circuit is the push-pull output, composed of two complementary transistors TIP41C and TIP42C, AC signal is greater than 0, TIP41C and TIP42C base voltage are increased (NPN-type base voltage increases on the conductive, the PNP-type base voltage decreases on the conductive), the TIP41C for the NPN-type, so the TIP41C conducts, the current can be output through the TIP41C. Similarly, when the AC signal is less than 0, the base voltage decreases, TIP42C (PNP type) conducts, and current can be output through TIP42C.
