Amperage and Voltage Rating of the Roadmaster Hy-Power Diode # RM-790

Question

Question:

Do you know if these are silicon or Schottky diodes and what a typical voltage is at a given current rating? Very frustrating that Roadmaster provides no voltage vs. current specifications and assumes all potential users are ignorant of such things.

Answer 3

If the two power sources are going to be on the same, input side of the diode then the current would flow through it without an issue. If you put power on both sides of the input side of the #RM-790 the current on the output side of the diode would…
