PROTON-ELECTROTEX is a global leader in the development and production of power semiconductors – diodes, thyristors, IGBTs, and also power units for various electric energy converters. The main goal of the company is to provide customers with modern, innovative and reliable power semiconductor products.

The company was founded in 1996, with the headquarters and main production facilities of the company being located in the city of Orel – 360 km South from Moscow. In 2010 the company’s R&D centre was formed in Moscow and continues to be a centre of excellence for developing innovative new devices and improving semiconductor technologies for ever demanding applications.

The main products of the Company are rectifying, avalanche and fast diodes and thyristors available in stud, disc and module design. PROTON-ELECTROTEX also offers welding diodes with high current load capacity and low static losses – available with or without ceramic housings. In 2016 the company launched IGBT modules in MIFA and MIAA designs.

All products produced by PROTON-ELECTROTEX are press pack designs. Press pack design ensures longer service time in comparison with soldered alternatives.

The manufacturing of semiconductor elements is based on two technologies: alloying technology and more advanced sintering technology – low temperature sintering of semiconductor elements with molybdenum disk using silver paste.

All Proton Electrotex semiconductor devices can be supplied ready-mounted on either standard-extrusion heatsinks, bonded-fin heatsinks, liquid cooled plates or specialist heatsinks to individual client specifications. Manufacturing capacity & technical expertise includes the development and production of power units for various applications based on semiconductor devices. Such units may optionally include air or liquid cooling systems, protection systems and integrated control systems.

Being the exclusive representative of the GvA Leistungselektronik GmbH (Germany) in Russia and CIS countries, PROTON-ELECTROTEX offers ready-to-use complex solutions for the production of three phase invertors needed for various projects in power electronics.

History of Proton-Electrotex

1996 — The year when Proton-Electrotex was founded. The company was created by specialists having vast experience in microelectronics. The first independent project of the new team was production of fast semiconductor devices in 1996.

1997 — In 1997 due to growing demand for pre-fabricated assemblies with heat sinks the company launched mechanical production. As soon as by the end of 1997 more than 10 000 of various power assemblies were delivered to customers.

1998 — In 1998, only 2 years after the company was created, it became the leader of Russian electrotechnical industry. It signed contracts with the largest Russian companies such as Severstal, the Urals Electrotechnical Plant, Russian Railways and the Ministry of Nuclear Energy of Russia.

1999 — Launch of frequency converters for asynchronous electric motors.

2002 — Proton-Electrotex established contacts with GvA Leistungselektronik GmbH that became our first foreign representative. Today Proton-Electrotex has more than twenty representatives all over the world.

2003 — Launch of power semiconductors in module packaging.

2006 — Trading House Proton-Electrotex was created to provide our foreign partners fast, high quality service. Today it includes more than twenty high-qualified specialists in marketing, sales, purchase and logistics of semiconductor devices.

2007 — Ecological management of the company was certified according to requirements of international standard ISO14001:2004.

2010 — Launch of Joint Venture Hebei Proton-Electrotex Electronic Co., Ltd in China’s province Hebei.

2010 — Proton-Electrotex opens its Moscow R&D Center.

2015 — Introduction of a business process management system Elma helping the company to optimize cooperation among its business structures, planning of resources and project control.

2016 — Long-anticipated launch of MIAA and MIFA modifications of IGBT modules. Previously 95% of IGBTs were imported to Russia from abroad.
