Rectifier Stud Diode D271-500 AS ENERGITM is general purpose diode. This is a power p-n junction diode designed for converting DC and AC currents up to 500A with frequency up to 500Hz in circuits with voltages up to 600V – 1200V (voltage class from 6 to 12). Diode package – SD7, mounting standard thread – М24х1.5, (on request, UNF thread 3/4"-16UNF-2A), weight – 465 g.

Diodes are supplied in stud design. Polarity of the diode is marked by a polarity symbol on the case.
Forward polarity diode – the threaded base of the diode is the Anode, the flexible power lead is the Cathode.
Reverse polarity diode – threaded base is the Cathode, the flexible power lead is the Anode.
Forward polarity is not indicated in the part numbering; Reverse polarity is indicated by an "X" in the part numbering.

This power diode can be an alternative product, replacement, analog, equivalent for other types diodes 450A, 470A, 490A, 500 amp in a stud mount package.

Air and water heat sinks are used to cool the diodes. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of diode during assembly, heat conducting paste is used.

The diodes have a hermetic ceramic housing isolating the functional part and the semiconductor element from mechanical impacts and environment. Stud screw fit diode with a flexible power lead. Stud diodes are notable for their ability to be used on moving parts.

Heat sinks for power stud diodes:

Heat sinks (radiators) are used for cooling of power semiconductor devices in stud design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

See for more information about heatsinks: "Air-cooled heatsinks for stud devices".

I'm Gizem, I'm a chemical engineer. I'm interested in making ceramic stuffs as a hobby. Would you please give some explanation about my questions below;
1) If I only mix SiO2 and Fe2O3 (3:1), can i get a suitable product without using other components?
2) Can i use water as fastener? or would you suggest me another fastener?
3) At which temperature should i mix them?
Thank you for your interest, Kind Regards

Hello, Gizem. The mass of ceramic is produced by grinding and mixing with water of different components: clay, feldspar, sand, kaolin. The proportions of these materials are different percentages, depending on what and with what characteristics you need to get a ceramic mass.
Each manufacturer of ceramic mass has its own recipes and its own raw materials, which are available in its region.
There are also books on ceramics that specify the chemical composition and approximate recipes for ceramic masses.

Is It need to apply vaselin or thermal past at Thyristor surfaces then attach to radiator/current leading parts?

When assembling thyristors, diodes with heat sinks, it is recommended to lubricate the contact surfaces with a thin layer of heat conducting paste to improve the heat transfer parameters. But this is not a prerequisite for assembly.
