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

19 out of 20 good
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).

Keeping them handy in case of a lighting strike.
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.

quality for price
worked great. purchased them for antenna

Ok
Not all of them work. Typical hit and miss quality

1998 k1500 4 high beam conversion
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.

Junk
Junk, don’t buy these. They work for a minute then you have current flow in both directions. Totally defeats the purpose of a diode.

Low forward biased voltage drop.
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.
