Tnisesm 20 Pcs 20SQ045 20A 45V Schottky Blocking Diode, Rectifiers Diode,Diode Axial Kit for Solar Panel

got what they promised .

Seem to work fine to convert 1998 K1500 to keep Lo beams on when Hi beams are on. I have LED bulbs for Hi and Lo beams so not sure these would carry halogen beams.

19 out of 20 tested good using a Fluke 115 DMM set to diode test mode. The one failure was a shorted unit (shorted forward biased yet showed OL when reverse biased, either way a failed unit).

Not all of them work. Typical hit and miss quality

Ok

I used these as flyback diodes for a 24V 5A DC motor I am running. They are quite large. Unfortunately, they were mislabeled. They came in a strip, with one side being held with red paper and the other side with gray. I took this to mean that the red side was voltage in and the gray side was voltage out. I assumed if the current went the other direction, then the diode would kick in and block the voltage. The reverse is true, which led to me getting extremely frustrated trying to get my simple circuit working. However, once I solved the problem it appears to work as a flyback diode with my limited testing.

I live off-grid in an Arched cabin that is solar powered. During the summer monsoon season, we can have some wicked lightning storms. My cabin has been hit once already. Fortunately, my solar panels were not damaged. When solar panels are hit by lightning, the most common failure is shorting of the internal Schottky blocking diodes inside the little black box on the back of the solar panel. I ordered these Tnisesm 20A, 50V Schottky diodes to keep on hand in case my panels should be damaged by a lightning strike in the future. Having spares on hand will allow me to get my solar array operational again with little down-time. I tested all 20 diodes with a transistor/diode tester. They all tested well within published tolerances.

Tested all 20 pieces with forward conduction and reverse block, as required. Forward voltage drop was between 100 and 192 millivolts when tested with diode test function on a multimeter. Germanium / Shottky type diodes usually 200mv (0.2v) or less per design. Silicon diodes are designed for a 700mv forward voltage drop when conducting. These will be used in a a12V automotive application to block reverse voltage from auxiliary circuits from back-powering existing circuits. Lighting and signaling circuits and relay control will not exceed published ratings.

Best quality. Good product.

bon

Works fine

Used to modify ATV headlight so that high and low beams activate at the same time. Was easy to solder, works as expected.
