Although Surface Mount Transistors are not strictly “Chips,” they look like “chips” and since these have the word “chip” in their definition, I have decided to include them in this Data Book.
The list is very big and only a short-form of the most common types have been listed here. The full version can be found on the internet: HERE.

Identifying Surface Mount Transistors is very difficult as their size is extremely small and the letters and numbers are very difficult to read. The same letters and numbers can be used for different types, depending on the manufacturer and the size of the device - so it’s very complex.
