PCB layout and Components layout of 120W supper bridge Power Amplifier using TDA2030

This circuit is designed by using TDA2030A circuit as driver to power transistor output to applied to out up 30 watt.
– then take both circuit to bridge together, makes we have the power output up to 4 times and have even maximum power output is 200Watt.

May don’t be defeated because this circuit give the electric power about 120W that load 2 ohm. When see the circuit will think use important equipment be. Must use power supply source that be appropriate about +15V and -15V that current 2Amp. Besides should use heat sink at have the size is appropriate IC TDA2030 and Q1-Q4 BD249,BD250 for see the circuit has already. Build easy must not fine decorate anything. Request a friend has fun Power Amp Super Bridge 120W by IC TDA2030 please sir.

– The advantage of this circuit, the voltage of the power supply is low (compared to other circuits. Watts are equal in size), so I used the low voltage capacitor, smaller, and cheaper.
– As can be seen from the circuit, we enter a signal input at pin 1 is side single. With pin 1 of IC2 (TDA2030) is connected to ground, And the output signal fed back to the inverting pin (pin 2) of IC2, Allow us to signal with opposite phase, input to the amplifier is one automatically.

How to build

Soldering Electronic Components to the right, onto the PCB as shown in Figure 2. Then install the power transistor to the heat sink. By Vice insulating sheet mica. To prevent a short circuit on the heat sink neatly.
When certain everything must be right, it was the power supply to the circuit, in order to use it, without having to adjust the circuit.

  1. Hi
    my english is poor … sorry .
    I read this article.
    It is possible to make this amplifier circuit with MOSFET Transistors

  2. i have made this circuit but it did not worked what the problem is there i do not know. however i shall try again to check it up. then will comment.

  3. i have made the circuit bridge120W by i.cTDA2030 as per the circuit and pcb given but it does not work why? i do not know all connections and wiring has been checked could any help me in this matter

  4. i have made the circuit bridge120W by i.cTDA2030 as per the circuit and pcb given but it does not work why? i do not know all connections and wiring has been checked could any one help me in this matter

  5. Pin 2 of two IC TDA2030 mustn’t connect Power.The Power will be connected with pin 5 of two IC TDA2030.Negative (pin 2) pole and positive pole(pin 1) connect with Audio signal…

  6. The problem is on the 2030 chip you have pin 3 and 5 reversed . Pin 1 is + and pin 5 should be on the same side in the schematic. Pin 2 is – and pin 3 should be on the same side in the schematic. Easy mistake

  7. Whis it? In the parts list you show c2,3,4,5,7 as 0.022uf but in the schematic you show them as 0.22uf. There is a big difference. Also in the parts list you have c1 and c6 as 0.0015 uf 50v and 10 uf 16v but the schematic shows them as both 0.22 uf . Can u pleas write me with the correct info? What else is wrong with the project? Help please. I bought all the parts but can’t assemble until I know.

    Thank u

  8. There is little mistake in the circuit.if the output is 120watts then the power transistor getting DC+ voltage via TDA2030 ? It must be in parallel to 2.2ohms supply. it will not work in 6volt DC. It requires 12V/7Amps free from rippling DC.

  9. yeh… i hav made dis circuit…
    the sound quality is nice.
    but the bass reflex is very poor..
    i replace both TDA2030A IC to TDA2050..
    and added one 1mF caps at the (+ve) input signal
    and added one 2000mF caps at the output signal..
    now the bass and the output power is increased to more… then before it has.

  10. Hi everybody,
    The circuit has many problems and it should be rectified before building this.
