Rectifier Diode D143-1250 AS ENERGITM is general purpose disc diode. This is a power p-n junction diode designed for converting DC and AC currents up to 1250A with frequency up to 500Hz in circuits with voltages up to 1000V – 1800V (voltage class from 10 to 18). Diode dimensions ØDxØdxH – 60x37x20 mm (outer case diameter X contact surface diameter X case height), weight – 240 g.

The anode and cathode of the diode (polarity) are determined by the symbol on the case. Diodes are in a industry-standard ceramic press pack disc (capsule, tablet) housing. This rectifier diode can be an alternative product, replacement, analog, equivalent for other types diodes 1100A, 1150A, 1200A, 1250 amp in a disk type package.

For cooling during the operation of power semiconductor diodes they are mounted with coolers (heat sinks). Depending on the amount of heat generated and the working conditions of the semiconductors, either natural air flow cooling or forced cooling can be used.

When assembling, the necessary clamping force Fm specific for each type of diode case (indicated in the parameter table) must be provided.

Semiconductor diodes disc type are used in power equipment – power and control units, power regulators, converters (e.g. melting furnaces), controllers where fast switching and control of currents is necessary.

Heat sinks for power disc diodes:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc 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 O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".

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.
