Products SEMIKRON product range consists of 11,600 different power semiconductors from 1 kW to 10 MW, including chips, discrete diodes/thyristors, power modules (IGBT / MOSFET / diode / thyristor/CIB/IPM), driver and protection components and integrated subsystems. As a significant innovator in the power electronics sector, many of SEMIKRON progressive developments have been accepted as industrial standards. Amongst other developments SEMIKRON invented the world's first isolated power module, the SEMIPACK, of which 56 million are presently in use. Important innovations of the organization: 1959 First silicon diode and silicon wafer 1963 First encapsulated bridge rectifier, a revolutionary plastic bridge which established itself in the entire electronics industry 1964 First 1 Amp plastic diode for direct PCB assembly for use in radios and television sets 1967 First thyristors for variable speed DC-drives, AC-soft-starters and three-phase AC-converters 1992 SKiiP, the first IPM (Intelligent Power Module) with integrated driver and solderless SKiiP pressure contact technology; 100A -1200A / 600V - 1200V for applications with high power requirements 1992 CAL diode, fast soft diode, featuring the best characteristics as free-wheeling diode 1996 MiniSKiiP, first integrated IGBT power converter circuits with solderless spring contact technology 2001 Integrated converters for hybrid electric vehicles 2005 SEMiX rectifiers and converters with solderless spring contacts as electrical contact 2008 SKiM, 100% solder-free IGBT module for electric and hybrid vehicles Applications Today, 44 Gigawatt wind capacity is powered by SEMIKRON technology. 94 Gigawatt (Source: BTM Consult ApS, 03/2008) is the total installed wind capacity since 1993. EMIKRON inside has become a trademark for new markets such as renewable energy and hybrid vehicles as well as industrial applications such as electric drives, welding machines, lifts, power supplies, pumps, conveyor belts, trains and trams. As a significant innovator in the power electronics sector, many of SEMIKRON's progressive developments have been accepted as industrial standards. State-of-the-art technology Spring contacts allows for electrical contacts without soldering. Avoiding solder fatigue, spring contacts are resistant against shock, vibration and corrosion, and provide high temperature cycling in harsh industrial environments. The module is easily assembled to the control PCB only with screws. By pressing the PCB to the module the electrical contacts are established. When using pressure contact technology, the soldered copper base plate and solder layers are omitted. Therefore modules with SKiiP Technology have fewer solder layers and have a 25% lower thermal resistance compared to leaded modules. This guarantees a longer service life time. SiNTER Technology in combination with pressure contact technology results in an increased service life time of a module because critical solder is omitted. The chips are not leaded but sintered by a cold weld to the ceramic. The operating chip temperature of 175C is only 18% of the disassembly temperature of the sinter layer (solder: 60%). This shows that compared to the solder layer, the sinter layer will not fatigue over time in the application. Quality & Environment SEMIKRON has an integrated management system and is certified according to DIN EN ISO 9001:2000, VDA 6.1, OHRIS Work Security Management. The environmental management system is according to DIN EN 14001 and EMAS. All SEMIKRON products do not contain Mercury, Cadmium, Hexavalent Chromium, PBB or PBDE. All products are lead-free according to the RoHS directives. eCommerce Via an associated company of the SEMIKRON Group it is possible to order online at the power semiconductor portal SindoPower. Social engagement In memoriam to the wife of the company founder, a registered association called artin Care e. V was started in the eighties. The association provides for orphans in Brazil. Additionally projects in India, South Africa and other parts of the world are supported.
