Hi - I'm interested in making a active clamping circuit to reduce spikes seen by sensitive electronics on a noisy supply line. Essentially think TVS/zener but with better tempco, steeper IV curve, etc. Just like a TI flat clamp, but higher power capabilities.
One thing that I was not sure about is which sort of transistor would be best. My first thought was an SOA optimized N-FET like some of the nice Nexperia parts. But are there other transistor types I should be considering? I had trouble finding SOA curves for BJTs. Is it possible they would work better for this? Or something else?
Thank you!
