Thyristor Modules SKET Semikron Replacement

Thyristor Modules SKET Semikron have a monolithic design with a single topology of semiconductors (one switch): single thyristor. Used in DC and AC circuits with loads to 819A and reverse pulse voltages up to 2200V.

Thyristor Modules AMET AS ENERGITM is a replacement, equivalent and alternative semiconductor device for SKET Semikron.

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

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

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

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.

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.
