I used to test transistors VCBO using a high voltage transformer,a
varic, a limiting resistor, a diode and a current sampling resistor.
An oscilloscope in XY mode was used, with the X calibrated in peak
volts and the Y to detect the breakdown current.
I don't remember the criteria to set the value of the limiting
resistor. I am testing 100 W TO3 Ge transistors with 100 K as limiting
res.
and the knee is not well defined (rounded).
Perhaps that is normal for Ge .
Will appreciate any help.
