I have an switching circuit containing a transistor to switch the inductive load. There is a miller effect compensation capacitor (C1) in parallel with a base resistor. (The values of the two components have been deliberately increased to better show the effect.)
What happens is, that the base voltage gets negative if the signal source voltage is 0V. It could get below -5V. The datasheet of this particular transistor states that VEBO maximum rating is 5V.
Is this already exceeding it's maximum ratings for VEBO?
Simulation in LTspice shows a bit different (worser) results.
There you can see additional ringing 6 times the frequency of the signal generator in this particulary case. And also presumably because of back emf there are (desired) spikes in collector voltage that gets capped by the 3 zener diodes at 36V.
