Driver circuit diagram for PNP and NPN transistor

Electronics Help Care August 29, 2025 Amplifier Diagram

This is the driver circuit diagram for the PNP and NPN transistors. This circuit runs with positive, negative, and ground voltage. We can use 25-0-25 voltage to 60-0-60 voltage. 2sc5200 and 2sa1943 are the best transistors for this board. We can also use C5198 and A1941. We can use a minimum of one pair to 10 pairs of transistors.

How to make an amplifier circuit diagram using a transistor. This circuit can produce any watts we want. We can use a 30-0-30 voltage to an 80-0-80 voltage using this type of diagram. Here, use two circuits: one for the driver and another for the transistors. It’s a mono diagram. Here need PNP and NPN transistors. We can use various transistors. like 2sc5200 and 2sa1943. or A1941 and C5198. or 2sc2922 and 2sa1216.

how to amplifier circuit diagram using transistor

This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
