Power Rectifier Diode Д132 Series (D132 Series)

Power rectifier diodes of the D132 series are stud diodes designed for general-purpose applications, capable of converting both direct and alternating currents up to 80A (depending on the series) with a frequency of up to 500 Hz in circuits with voltages ranging from 100V to 1600V. The polarity of the diode is identified by an icon on the case. In the case of direct polarity, the diode’s base serves as the anode, and the stud terminal as the cathode. Conversely, for reverse polarity, this relationship is reversed, and the marking includes the letter “X.”

The diodes of the D132 series feature the RSD3 case type with an M8 thread and a weight of 27g. Notable type designations for the D132 series include D132-50, D132-50X, D132-63, D132-63X, D132-80, and D132-80X. For effective heat dissipation, these diodes are assembled with coolers (heat sinks) using threaded connections. To ensure reliable thermal and electrical contact between the diode and the cooler during assembly, it is crucial to adhere to the specified tightening torque (M2). Additionally, heat-conducting paste can be applied during assembly for enhanced heat dissipation.

D132 power diodes find application as rectifying and demagnetizing diodes, mitigating the adverse effects of switching overvoltages. They are commonly utilized in low-voltage rectifiers for welding and galvanic equipment, uncontrolled or semi-controlled rectifier bridges, and electric generators for industrial and transport applications. Manufactured to withstand temperate, cold (UHL), or tropical (T) climates, these diodes fall under accommodation category 2.
