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.

20 Amps??
I intended to use these rectifiers at 12 V with a maximum current of 5 A. My first test was the reverse current at 12 V. It tested at 22 uA, which is fine. My lab power supply is limited to 3 A, so I tested the forward voltage required to drive 3 A forward through the rectifier. It was about 1.0 V forward. So at 3 A, the power dissipation is about 3 W. At 20 amps, the power dissipation would be higher than 20 W, since the forward voltage would go higher.. In my opinion, that is why they are getting so hot. They do not seem usable at 20 A, as claimed.
