Q. How do I identify leads on older transistors from their markings and case types?
A. Transistors come in a variety of shapes and sizes.
Some have 3 leads, some have 4. Some are PNP, others NPN. Some are silicon, others germanium based.
Most types are current driven, while some, like FETs (Field Effect Transistors) are voltage driven.
In the midst of all this variety, it is difficult to both select and correctly use the right transistor.
To add to that, the same case can have different lead arrangements for different transistors.
So, without correct diagrams and charts, it is little short of guesswork to get it right, and unfortunately, getting it wrong can result in damage to the transistor.
Following enquiries from visitors it was decided to publish this information as a referance source.
We hope you find it useful in identifying and using your older components.
Originally published around 1980 in Practical Electronics, this chart shows case types, lead markings and similar transistor numbers.
Key to lead outs: b=base e=emitter c=collector g=gate d=drain s=source
