Csm5b2 datasheet transistor bd139
Coach jeff spaletta
I got this low power transistor that I want to make a class-A amplifier out of, but I'm having a really hard time with it. It seems not to behave much like what I expect from a transistor. The transistor came in a TO-126 package. I've never seen one like it, so I had no idea which side was the emitter.
