Much lower than newbie, in pipe fitting almost everything is in line and parallel connections rarely effect the main. The diode is essentially a FET with the gate shorted to the source...I barely know what this means! The following explains the application and failure. I need help. Would someone tell me what I need to do to make this work? Thanks plumber. = Hello, I recently purchased a current limiting diode, but it did not limit the current. I am sure the fault lies with me and not your product. I need to buy more, but first I must find out what went wrong. Please forgive the lack of proper terminology as I describe what I did: this is for electrolysis, in which I need to keep the current from climbing above 1.5 mA.
30 volt dc unregulated power (wall adaptor) + output to striped end of CDL. (+) output from diode then goes through multimeter (in line) and then out to the (+) anode. - output from wall adaptor goes through (-) side of multimeter and then to the (-) cathode. Starting current was
228u. As the process advanced, the current climbed past 2.88mA after the tenth hour. The CDL was rated for a current limit of 1.2mA .Stock #610-1n5299 / MFG PN 1n5299 (Central Semi Conductors) I will test the diode a little later and report back. How susceptible are these diodes to static discharge? I was reasonably careful, touching my grounded project box as I handled and soldered the diode in place. Didn't use a grounding strap. So please, tell me what basic circuit knowledge I messed up with? "series" / "parallel" did I need a Zen. diode or resistor somewhere? I know the set up was ultra simple...made sense to a plumber! Any input would be appreciated.
thank you for your time
