100W Amplifier Circuit Diagram using TIP36 Transistors

Introduction

In the world of electronics, amplifiers play a crucial role in boosting the power of a signal. One such amplifier is the 100W Amplifier Circuit, which can deliver a significant power output while maintaining excellent fidelity. This article will explore the circuit diagram of a 100W Amplifier Circuit that utilizes dual TIP36 transistors in the output section, BD139 and BD140 transistors in the driver section, and a pair of MPSA92 transistors in the preamplifier section.

Specification of Transistors:

1. TIP36 Transistor: The TIP36 is a high-power PNP transistor capable of handling up to 25A of collector current. This transistor is specifically designed for audio amplifier applications, making it an excellent choice for the output stage of the 100W Amplifier Circuit. The TIP36 transistor ensures a robust and reliable amplification process, contributing to the circuit’s high power output.
   
2. BD139 and BD140 Transistors: The BD139 and BD140 are complementary NPN and PNP transistors, respectively. These transistors are widely used in the driver stage of audio amplifiers due to their low power dissipation and high current gain characteristics. The BD139 and BD140 transistors help in driving the TIP36 transistors effectively, ensuring the required power transfer across the amplifier circuit.
   
3. MPSA92 Transistor: The MPSA92 is a high current gain PNP transistor that excels in low noise and high-frequency applications. In the preamplifier sections of the 100W Amplifier Circuit Diagram, a pair of MPSA92 transistors helps in amplifying and conditioning the input signal before it reaches the driver stage. The low noise characteristics of the MPSA92 transistors contribute to maintaining fidelity in the amplified sound.
