Features: planar passivated chips; very low leakage current; very short recovery time; improved thermal behaviour; very low Irm-values; very soft recovery behaviour; avalanche voltage rated for reliable operation; soft reverse recovery for low EMI/RFI.

Rectifier diodes convert DC and AC currents up to 12.1 kA in circuits with voltages up to 7.2 kV. Their main applications are rectifiers for variable large AC drives, traction converters, trackside substations, welding and DC power supplies. Devices are primarily intended for applications with line frequencies up to 500Hz.

The diode has an industry standard ceramic housing making it easy to integrate the device into existing equipment. This diode has a disc housing with pressure contacts. The polarity of the diode (anode, cathode) is determined by the icon on the case. The technical specifications, part numbering guide, datasheets PDF, outline drawings for rectifier diodes are listed below.

Rectifier Diodes AS ENERGITM have the following features: low static and dynamic losses, high values of VRSM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 10 to 15000 A, high resistance to thermal and electric cycling.

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