It is commonly used in power amplifiers, voltage regulators, and high current switching circuits.
The 2N3055 transistor has been in use since the 1960s and is still widely used today due to its reliability and ruggedness. It is an NPN (negative-positive-negative) transistor with a maximum collector current of 15 amps and a maximum collector-emitter voltage of 60 volts. TECHNICAL SPECIFICATIONS OF NPN EPITAXIAL PLANAR TRANSISTORĢN3055 is a bipolar junction transistor (BJT) that is widely used as a power transistor in various electronic circuits. NPN TRANSISTOR FOR POWERFUL AF OUTPUT STAGES This is enough for this case.15 AMPERE POWER TRANSISTORS COMPLEMENTARY SILICON 60 VOLTS 115 WATTSġ5 AMPERE COMPLEMENTARY SILICON POWER TRANSISTORS 60, 120 VOLTS 115, 180 WATTS A circuit Designer set in an unregulated power supply pattern. It is a 35V 4A Dual DC power supply circuit. Here is a power supply circuit of a 40W-50W OCL amplifier. VR1 serves as to adjust a bias voltage of the idle current to the circuit. This connection reduces crossover distortion as well. for Q4 acts as setting bias level of the output transistor which is instead Diodes same the normal amplifier circuit. Q3 serves to limit current, the general bootstrapped circuit that uses the RC. Such as a speaker cable short-circuited, by will acts as short the bias circuit of the output transistor is reduced so that it not works. Because the current flowing through the load too much. Q8, Q9 acting as the driver circuit to drives the power transistor Q10( MJ2955), Q11( 2N3055).įor Q6, Q7 acts as the output transistor protection circuit from damage. The transistor Q5 is the part second amplifier circuit, by has C3 is to feedback between pin base and collector, to prevent procreation oscillator way high frequency At emitter circuit has Zener diode is connected as maintaining a constant voltage 15V. The transistor( MPS9632) Q1, Q2 together to as a differential amplifier, By has R10, R4 and C2 together constitute the feedback circuit and defined an all gain ratio of a circuit. 40 watts Main Audio amplifier circuit using transistors
