Thyristor Modules MTT, ČKD Polovodiče Replacement

Thyristor Modules are monolithic design with dual topology of semiconductor thyristors (thyristor-thyristor type). Used in DC and AC circuits with loads to 290A and reverse pulse voltages up to 1600V.

Thyristor Modules AMTT AS ENERGI^TM is a replacement, equivalent and alternative semiconductor device for SCR Modules MTT Series ČKD Polovodiče.

The thyristor modules are housed in a standard industrial case making it easy to easy integrate of the device into existing equipment.

Modules has different internal constructions: soldered construction – the contact is established by solder layers; pressure contact construction – the contact is established by pressure, solder free assembly.

The modules are designed and assembled in high reliable pressure contact and in solder bond technology which addresses the specific requirements of cost and performance optimized applications.

Thyristor modules are used in various power equipment - power and control units, electrical drives, power regulators, AC regulators, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.

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

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 M_S

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 M_S has been reached.
