Module Semikron SKKH 91/14E is a dual thyristor-diode SCR module in a standard housing SEMIPACK 1.

Thyristor-Diode Module AMKH 91-14E AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for SCR module SKKH 91/14E Semikron.

The thyristor diode modules are characterized by high electrical and thermal cycling capability, meaning high reliability and long lifetime in intensive operation modes. The thyristor diode modules are housed in a industry-standard housing making it easy to integrate the device into existing equipment.

The main (power) terminals are on the top of the case and are marked as 123 (common anode-cathode, cathode, anode). The control terminals are marked as 4 (K1), 5 (G1).

Thyristor diode modules are used in various power equipment - power and control units, power regulators, AC regulators, DC motors control, AC motor soft starters, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.

Our modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.

Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.

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.
