WebWhat do you look at, to much leakage, HFe to low, or is the device OK as long as the tester can read it and it doesn't show up as a diode or something else it isn't. I Have a transistor with a tested HFe is 25, the spec's for this Germanium transistor show it to have an minimum HFe of 50. Is the 25 the actual figure or just how the tester is ... coins/ecif prm rcm netquery and webviewWebThe above one is a simple transistor tester circuit; wherein Quad2 input CMOS, NAND gate IC, CD4011B is the heart of the circuit.

It could be in the 100uA range. Simple testers, like the one in a DMM, and that AVR based "Transistor Tester" too, use very small base current (usually 10uA), and measure the collector … coinseed incWebemitter and base.
