Power Rectifier Diode Д261 Series (D261 Series)

The D261-250 power rectifier diodes are stud diodes designed for general-purpose applications, capable of converting both direct and alternating currents up to 250A with a frequency of up to 500Hz in circuits with voltages ranging from 2400V to 2600V. The diodes feature the RSD6 case type with an M20x1.5 thread and a weight of 0.265 kg. Notable diode ratings include D261-250-24 and D261-250-26.

These diodes are essential components in power supply circuits of electro-physical installations and energy converters. To ensure efficient heat dissipation, the diodes are assembled with coolers using a threaded connection. During assembly, it is crucial to adhere to the specified clamping force (tightening torque M2) to ensure a reliable thermal and electrical contact with the cooler. Additionally, heat-conducting paste can be applied during assembly for enhanced heat dissipation. The diodes are manufactured for use in temperate, cold (UHL), or tropical (T) climates, falling under accommodation category 2.
