Dual Diode Modules MDK

Power Rectifier Diode Modules AS ENERGITM are non-controllable rectifiers for AC/DC converters in monolithic design with dual topology of semiconductors (two switches): diode-diode type. Used in DC and AC circuits with loads to 1200A and reverse pulse voltages up to 3600V (depending on series).

The rectifier diode modules are housed in a industry-standard housing making it easy to integrate the device into existing equipment.

Part numbering guide for diode modules MDC

Installation recommendations for diode modules

The diode modules are characterized by high electrical and thermal cycling capability, meaning high reliability and long lifetime in intensive operation modes.

Circuit Diagram of Modules MDK

Rated range of currents of rectifier diode modules: 26A, 40A, 55A, 70A, 90A, 110A, 135A, 160A, 182A, 200A, 250A, 285A, 300A, 350A, 400A, 500A, 570A, 600A, 800A, 1000A, 1200A. Nominal voltage range: 600V, 700V, 800V, 900V, 1000V, 1200V, 1400V, 1600V, 1800V, 2000V, 2200V, 2400V, 2600V, 2800V, 3000V, 3200V, 3400V, 3600V.

The main (power) terminals are on the top of the case and are marked as 1, 2, 3 (common anode-cathode, cathode, anode).

The two-position modules have different switching circuits (electrical circuit diagrams): МDC – half-bridge; МТK – scheme with common cathode; МDA – scheme with common anode.

Rectifier diode modules MDA series are used in various power equipment - power and control units, power regulators, AC regulators, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.

Recommendations for mounting power modules

Heatsink and Surface Specifications, Preparation

In order to ensure good thermal contact and to obtain the thermal contact resistance values specified in the datasheets, the contact surface of the heat sink must be clean and free from dust particles. It is useful to clean the mounting surface of the heat sink with wipes and an alcohol cleaner, e.g. isopropanol, right before the mounting process. The following mechanical specifications have to be met:
– Unevenness of heat sink mounting area must be ≤ 50μm per 100 mm
– Roughness Rz: < 10 μm
– No steps > 10 μm

Heat sink surface specification

Applying Thermal Paste

Recommended to use stencil printing in order to apply thermal interface material. Recommended to use thermal paste thickness in the range from 50 μm to 100 μm. Applying thermal paste by means of roller is not recommended for mass production as reproducible of an optimized thermal paste thickness cannot be guaranteed.

Mounting torque on heat sink MS

To secure power modules, the use of steel screws in combination with suitable washers and spring lock washers or combination screws is strongly recommended. The specified in datasheet torque value must be observed.

A pre-tightening torque and retightening to the given torque value is recommended. For the screwing process the speed has to be limited and soft torque limitation is recommended to avoid torque peaks, which may occur with pneumatic screwdrivers.

Example of mounting order

The screws must be tightened in diagonal order with equal torque in several steps until the specified torque value MS has been reached.

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?
Maksim 27.06.2022 at 10:39

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.
