Diode modules are designed for energy converters and other DC and AC systems of various power electrical installations.
Nimatek offers a wide lineup of single- and dual-component diode modules for voltages VDRM/ VRRM from 1000 to 6500 V and currents IFAV from 155 А to 1000 А. Such a wide range allows to use these modules in multiple various applications.
All diode modules by Nimatek have a pressure-contact design that ensures high resistance to cyclic loads and easy mounting.
The modules have an electrically insulated copper baseplate that ensures optimal heat distribution and dissolving. Besides, it is possible to mount several modules on the same heatsink without any additional insulation, significantly reducing the assembly size.
The modules have a high electric and thermal cycling capability meaning high reliability and long lifetime in intensive operation modes.
Dual-component diode modules can have several circuit schemes designated as MD3, MD4 or MD5 in the product number. Electric layout of the modules is shown in attached datasheets.
Today Nimatek is one of the leading manufacturers of power modules in Europe. The manufacturing process is certified for compliance to UL, ISO 9001, ISO 14001, EcoVadis standards and passed audit of the largest end-user companies in the world.
