Regarding the replacement of 2SC945, what can be used to replace c945, and what model can be used instead of c945?

2SC945 can be temporarily replaced by commonly used cs9014 when it burns out, and triodes of cs9013, cs9014, 2n3904, C1815 and other types can be directly replaced. The pin arrangement of these types of transistors is somewhat different, so be sure to pay attention to the 2SC945 pins when replacing.

2SC945 Chinese information: 2SC945 is just an ordinary general-purpose NPN transistor that can be replaced by ordinary transistors with general approximate parameters, but the model to be replaced should be selected according to the working conditions of the circuit. Generally, most of the ATX DC low-voltage parts are The low frequency circuit is used as a switch tube or a simple voltage regulator (or voltage regulator) in the circuit. If it is the cooling fan speed regulation circuit or the P/G 5V reference, it can be replaced with a domestic 9013. If it is a voltage output The circuit at the terminal (the most classic is +3.3V output) should be replaced by a tube with higher power such as 8050 considering the power problem. Of course, other ordinary triodes can be used, but pay attention not to solder the wrong ECB polarity.

NPN transistors, left to right ECB for low speed switching, high frequency amplification. Current amplification factor: about 200 TO-92 package, generally speaking, the triode will not have the pin sequence of EBC.

2SC945 related knowledge:

1. Triode, the full name should be semiconductor triode, also known as bipolar transistor, crystal triode, is a semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a large amplitude value, and it is also used as a non-contact Click the switch. Transistor is one of the basic components of semiconductor, which has the function of current amplification and is the core component of electronic circuit.

2. Transistors (hereinafter referred to as triodes) are divided into two types according to materials: germanium tubes and silicon tubes. Each of them has two structural forms, NPN and PNP, but the most used are silicon NPN and germanium PNP two kinds of triodes, (where N means adding phosphorus to high-purity silicon, which means replacing some silicon atoms, in the voltage Under stimulation, free electrons are generated for conduction, while p is added to replace silicon with boron, which generates a large number of holes for conduction).
