Hello,
Trying to design a circuit using a biased bjt. I am in the middle of prototyping a standard bjt npn, and pnp discrete to92 transistor. I am quesioning the results i am gettting and am trying to find out a way of being able to tell the collector from emitter. I can test to the 2 pn junctions to tell pnp from npn, but am not sure how to tell between the C and E. The datasheet shows the t092 package with the flat front and 3 dots, and says bottom view, i think that the bottom view means that i am looking at the pin from the bottom as they are entering the body, but am not sure.
The reason i question which is which, is because i am getting identical results when switching 5v to -5v VCE. I dont believe it is a good idea to do this, but am testing the parameters of the transistor. Also, can you tell me what would cause a high current output from base to emitter?? In a certain configuration the collector is being bypassed, and the base is running 500ma of current, way too much for standard operation.
What about good books, any good recommendations for different byassing techniques of BJT's?
