Proton-Electrotex is one of the world's leading manufacturers of power semiconductor devices. The company has a complete production cycle, sophisticated infrastructure, modern production lines, testing equipment and clean areas.

The main products of Proton-Electrotex are rectifying, avalanche and fast diodes and thyristors in stud, disc and module design, IGBT modules, testing equipment, drivers, heatsinks and power stacks.

The entire manufacturing cycle is divided into four main stages allocated to separate substructures of the company:

• production of diffused semiconductor elements including silicon wafers polishing area, diffusion process area and lithographic processing area.
• production of elements with thermal compensator including alloy and evaporation processes, bevel polishing and bevel jet etching.
• semiconductor element measurement including measurement systems to determine static and dynamic parameters in the entire range of device operating temperature.
• assembly of the disc, module and stud devices as well as power assemblies with heat-sinks including clean processes of semiconductor assembly, encapsulation and approval tests.

The product portfolio of Proton-Electrotex covers stud, welding and disc diodes. These devices are actively used in electrical and electronic systems, DC and AC circuits, in resistance welding machines.

 The diode offer is available in a separate section of the product catalogue.

Another important business of ​​Proton-Electrotex is production of power semiconductor diode and thyristor modules. This type of devices is used in energy converters, DC and AC circuits of power plants. The company's products feature high thermal and electric cycling resistance and ease of mounting due to the pressure contact design. It is possible to install several modules on one heatsink, significantly reducing the overall assembly dimensions. Diode and thyristors modules are commonly used in AC regulators, power supplies, electric drives, DC motor controls.

The bipolar power semiconductors division of Proton-Electrotex has a full production cycle, sophisticated infrastructure, modern production lines, testing equipment and clean areas.

Manufacturing of IGBT modules was launched in 2016. Currently Proton-Electrotex produces modules in the MIDA, MIFA and MIAA housing. These types of devices are designed to switch powerful loads and are used in converters and drives of electric motors of small and medium power. IGBT modules are widely used in voltage inverters for solar panels, AC motors and wind turbine inverters.

 The IGBT modules offer is available in a separate section of the product catalogue.

 To order IGBT modules by Proton-Electrotex please fill in the following form.

Proton-Electrotex has a specialized laboratory for operational reliability tests. Its main tasks are to conduct classification and periodic tests, reliability tests, the devices lifetime tests, as well as providing technical support to the customers.

Laboratory of Proton-Electrotex has passed a certification confirming that it meets all the conditions necessary to perform measurements and QA testing. Such certification grants the company a right to provide power semiconductors testing services to third-parties.

The measuring equipment manufactured by Proton-Electrotex is designed for all types of bipolar power semiconductor devices including diodes, thyristors and IGBT modules in various housings – disc, stud or module. This equipment is also used for measurements of housingless semiconductors and tests of power assemblies.

All production processes strictly follow requirements of the quality management system (ISO 9001) and environmental management (ISO 14001).

Manufacturing of power semiconductors at Proton-Electrotex is adapted for customization. The company is able to group devices by their parameters, to provide custom wire connections, and to manufacture products with unique sets of properties ideally suited for various industries

To optimize the manufacturing process, to attract and use production, human or financial resources in a rational manner, the enterprise has implemented an ERP system containing manufacturing modules for tracking the production progress, resource allocation and a planning unit. 

Products made by Proton-Electrotex are highly appreciated both on the Russian and global markets of power semiconductors. Devices by Proton-Electrotex are the winners of multiple prestigious and respected competitions and ratings. Long-term customers of the company include ABB, Enercon, Schneider Electric, Electrotherm, Inductotherm, BELAZ.
