I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Introduction to C945. You will see a detailed description on the basics of the transistor C-945 and its different parameters. I have already shared Introduction to MMBD914, 74HC245, NE556, LM348 and PIC18F4550. So, must go through these tutorials in order to have better understanding about different IC’s. C-945 transistor is basically a Negative Positive Negative (NPN) bipolar junction transistor.

C945 is usually used in the electronic circuits where there is a need of high speed transistor and a low current. C-945 has three semiconductor regions named as emitter, base and collector respectively. Since C-945 is a bipolar junction transistor, its base is doped with the positive or P type semiconducting material. Whereas, it collector and emitter both are doped with the negative or N type semiconducting material. When we apply voltage at C-945’s base, the current starts to flow between collector and emitter. C-945 transistor is an electronic equipment used for low power applications. C945 has a lot of amazing features. These features include low current, low voltage, good linearity, low noise, complementary to A733 and many more. C-945 bipolar junction transistor has a wide range of applications in real life. Some of them include high speed switching applications, amplification processes, low power applications and a lot more. I have also provided all these information of other IC’s in Introduction to L298, MC34063, LM386, TL072, UA741, 2N3906 and LM1458.  It is a low cost electronic component and is easily available in the market these days. It is most common equipment in the market due to its large range of applications. C-945 can also be used in two relay module used to drive different AC (Alternating Current) as well as DC (Direct Current) loads. If you want to work on C945 in Proteus, then you should download this C945 Library for Proteus. The further detail about C-945 transistor will be given later in this tutorial.

      • Hi! We use Google translator. We bought 20 pieces of transistors brand C945 (Y-G50). Two extreme curves at the output-curved legs. They have a base in the center. Most likely, the transistors with straight legs, where the base 3.On transistors class a-733 with straight legs base output-3.
