This is a 2-transistor amplifier circuit diagram using 2SC5200 and 2SA1943 transistors. This is one of the best pairs of amplifier transistors. This pair transistor can make 150 watts of audio output. It’s a mono audio circuit board. We can use here 25-0-25 voltage to 60-0-60 voltage maximum. positive, negative, and ground voltage needs.
The 2SC5200 (NPN) and 2SA1943 (PNP) are one of the most famous complementary transistor pairs in the world of high-fidelity audio. Originally designed by Toshiba, they are the “gold standard” for DIY and professional Class AB power amplifiers due to their high power handling and linear response.
Details about 2SA1943
2sa1943 Polarity is PNP. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Details about 2SC5200
2sc5200 Polarity is NPN. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
DIY stereo audio amplifier circuit diagram:
This is a DIY stereo audio amplifier circuit diagram. used only 2sc5200 transistors. only an NPN transistor. We can use the minimum 24-0-24 voltage to 50-0-50 voltage. It’s a stereo audio amplifier circuit diagram. Each channel got 100 watts of output. left channel 100w and right channel 100w.
The part numbers MJE15004 and MJE15005 appear to be related to similar but distinct power transistors, potentially leading to confusion with the widely known MJ15003 and MJ15004 series. Based on common component naming conventions and available datasheets, here is a breakdown: MJ15004 (PNP) and MJ15003 (NPN). The search results strongly indicate that MJE15004 is often a variant or a misinterpretation of the MJ15004 power transistor, while MJE15005 is highly similar to the MJE13005 switching transistor. The MJ15003 (NPN) and MJ15004 (PNP) are a popular complementary pair of silicon power transistors. Type: Bipolar Junction Transistor (BJT) Purpose: Designed for high-power audio amplifiers, disk head positioners, and other linear applications. They are known for providing low distortion in complementary designs. Package: Typically in the metal TO-204AA (TO-3) case.
