Introduction to C945

Introduction to C945
C945 is a Negative Positive Negative (NPN) bipolar junction transistor. It has three regions emitter, base and collector. Its base is doped with P type semi-conductor material. Emitter and collector are doped with N type semiconducting material. Its a low cost device and is very popular in the market due to its large range of applications. Its applications include fast switching, amplification, low power electronic circuits and many more. C-945 is shown in the figure given below.
- Moving from left to right pins of C-945 in the above figure are in an order emitter, collector and base.

- For the pinout diagram of other IC's, you must also have a look at Introduction to LM393, LM317, 1N4007, and LM335.
4. C945 Pin's Doping Material
- As we already know C-945 is a NPN bipolar junction transistor, i.e. it has both type of doping materials N-type as well as P-type.
- It base region is doped with P-type semiconducting material and is sandwiched between emitter and collector.
- Both emitter and collector are doped with N-type materials.
- The doping materials of all the regions are listed in the table shown in the figure given below.
5. C945 Ratings
- If we have not used any device before, we must know about its power requirements.
- We can estimate the power requirements of any electronic device with the help of its ratings.
- C-945 ratings are listed in the table given in the figure shown below.
6. C945 Features
- A device's popularity is directly related to its features.
- If a device is having more unique and beneficial features, it will be more popular among its competitors.
