Goldmine Electronics had a sale on USD5096F 35 Volt, 35Amp Schottky diodes (they’re now sold out), so I bought a handful. <\/p>\n
These are the old style all metal stud mount package, and come without any mounting hardware. The stud is 1\/4 x 28 threads, so I had to order some 1\/4 x 28 TPI nuts for them (standard 1\/4″ nuts are 24 threads per inch). If I have to mount them on a heat sink that is not isolated, then I will need a mounting kit with the mica washers, sleeve, metal washers, and solder lug.<\/p>\n
The cathode is the stud. These Schottky diodes will conduct several amps with only a few tenths of a volt forward voltage drop. They should be ideal for rectifying low voltages, or for a blocking diode for a solar panel.<\/p>\n
I measured one with a cheap DMM and saw they have quite a bit of reverse leakage. But this is normal for a high current Schottky diode, which is half of a normal diode.<\/p>\n
The big metal package with the pigtail and lug looks very impressive when bolted to a heat sink. It’s not the latest high tech MOSFET active rectifier that’s used in high efficiency circuits today, but it’s much more efficient than a regular diode.
