Transistor Tester


Posted on Aug 9, 2012

When building amplifiers, it is often necessary to test transistors, either to verify that they (still) work, or for some esoteric designs it may even be necessary to match certain characteristics. The design featured here is just what you need, and provides the ability to test: * Gain (also referred to as hFE or Beta) * Gain at various collector currents up to 5A * Breakdown voltage (with or without Rbe - value is selectable)

As with some of my other projects, this is not particularly cheap to build, but if my own unit is anything to go by will give many years of faithful service. (I have actually had mine for so long that the variable high voltage source was using a valve - i
