My stock of transistors which I have accumulated over the years was so disorganized I didn't know what I had or where it was located. So I rounded them up and put them in clearly labeled plastic drawer storage. While I was at it, I downloaded data sheets and made a spread sheet summarizing the most important parameters. The data summary seems so useful that I decided to share it with you.Transistors such as the 2N27 are so old it would be quite a coincidence if you had some of them. I include them in this list as a curiosity. I wonder if the first transistor to have a JEDEC number was a 2N1 or a 2N10. The 2N27, 2N28, and 2N233 are in a metal package that looks like a greatly miniaturized version of the HC6U quartz crystal package. I did not find a JEDEC designation for this package. If anyone knows of one please share your knowledge with me. I will pass it on here.
The numbers in red are currently available in a transistor assortment that can be found on Amazon and eBay. Here is an Amazon link. There are a number of these kits available. Which one you buy is up to you.
