I haven't done major testing but they do seem to be working fine in my dimmer circuit.

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.

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.

Not all of them work. Typical hit and miss quality

I used this as a blocking diode for a power supply. It has about 350mV loss in the circuit which is acceptable for this type of diode. The problem is that with just 10A of current, this thing heats up so much that there is a risk of burning old the diode. There is no way to install a heat shrink on this type of diode. It will work fine for currents less than 1A. I paid for a 20A diode even though I only needed 10A. Having this much surplus was not enough to avoid overheating. I will probably have to search elsewhere.

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