Dual Thyristor Modules SKKT, SEMIPACK

Power Thyristor Modules SKKT are monolithic design with dual topology of semiconductor thyristors (thyristor-thyristor type). Used in DC and AC circuits with loads to 570A and reverse pulse voltages up to 2200V (depending on series).

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

In order to satisfy various market demands, SEMIPACK family has three different internal constructions:

  • soldered construction (SEMIPACK 1) – the contact is established by solder layers;
  • bonded construction (SEMIPACK 0, 2, 3) – the connection between top electrode of the chips and DBCs is realized by bond wires;
  • pressure contact construction (SEMIPACK 3, 4, 5, 6) – the contact is established by pressure, solder free assembly.
Circuit Diagram of Modules SKKT

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 K1, G1, K2, G2.

SKKT thyristor modules 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.

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 quality declaration and certificate of conformity.

The final price of thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.

For questions regarding the acquisition of Power Modules, Thyristors, Diodes, send an email request to:

office@asenergi.com

And we will provide you a commercial offer for delivery.
For a large number, we will provide an individual price!!!

We are open to manufacture products at our production facilities
according to your requests and technical task.

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. For SEMIPACK we recommend 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 reproducibility 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 torque value must be observed.

Mounting speed max. 300 rpm max. 300 rpm max. 300 rpm max. 300 rpm
Pre-tightening torque 0.6 Nm 0.6 Nm 0.6 Nm 0.6 Nm
Final torque MS 4.25–5.75 Nm 4.25–5.75 Nm 4.25–5.75 Nm 5.1–6.9 Nm

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.

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.
