ES3D is a 200 Vrev 3 Amp 20nS fast recovery diode.
there is no such thing in this diode that with 24V you can get 5 seconds of reverse current.
what happens after 5 seconds? The data you are giving us is faulty or the diode is broken and should be replaced with another of the same part...
is it really a diode or a TVS? whats the part number?
if the voltage is high enough the TVS will conduct for as long as the voltage is high.
5 seconds is NOT reverse recovery
In a proportional solenoid the current needs to be controlled. Applying a varying DC is possible (like what you were suggesting) but it is also less efficient and the Power Dissipation is much greater than with pulse width modulation. If the coil current required is constantly varying by very...
