OLD Ex workshop spare parts and small manufacturing stock
These are some of my very old Germanium semiconductors, unused and stored on styro sheeting to protect the legs.
NOTE: The hFE values measured a quite low although many transistors designed for power switching have similar gains. I tried to establish what the manufacturers data provides and I found many conflicting hFE values quoted so these could be "below par" or then again, perhaps not.
At least they are not "cooked"
With these old devices (because I like to be sure and others have asked me for some basic testing to be done) I have grabbed a very basic transistor tester and the screen result is showing along with the device. The hFE measurement (DC current gain) has been printed onto the device casing, this is only a rough guide as the hFE will change depending upon temperature and Vce conditions.
If it is important for you to have particular devices (for matching as an example), please let me know which one(s) you would like to be supplied with, using the hFE as the reference.
