I need to build a simple device for TVS diodes testing. For that test, I need to generate an 80V pulse (10 us width I think) with 1 mA current limit. The things that come up to my mind are current source circuits. Ivee seen some based on more or less integrated current sources, or ones build with an op amp and a fet. The problem with them are low operating voltages (I would need to cascade them) and slow slew rates.
I would like to figure out either I understood correctly what is TVS test about and either my understanding for the solution is correct. What circuits would you suggest for this end? I would appreciate all help.
