DIY amplifier circuit using C5198 and A1941

DIY amplifier circuit using C5198 and A1941:

This is a DIY amplifier circuit using C5198 and A1941. It’s a mono-transistor amplifier that uses 2 transistors. In this circuit diagram, we can use 35-0-35 voltage to get 100 watts. Here, we need positive, negative, and ground voltage. 

C5198 is an NPN-positive transistor. Maximum Collector Power Dissipation (Pc) is 100 Watts. The Maximum Collector-Base Voltage |Vcb| is 160 Voltage. Maximum Collector-Emitter Voltage |Vce| is 160 Voltage. The Maximum Emitter-Base Voltage |Veb| is 5 Voltage. the maximum Collector Current |Ic max| is10 ampere. 

A1941 is a PNP-negative transistor. Maximum Collector Power Dissipation (Pc) is 100 Watts. The Maximum Collector-Base Voltage |Vcb| is 160 Voltage. Maximum Collector-Emitter Voltage |Vce| is 160 Voltage. The Maximum Emitter-Base Voltage |Veb| is 5 Voltage. the maximum Collector Current |Ic max| is10 ampere. 

The circuit diagram is 

 

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