Russian Avalanche Diode Disc DL153 Series

DL153 diodes are powerful low-frequency avalanche rectifier diodes with a pill-type design, suitable for general-purpose applications. They convert both DC and AC currents up to 2000 amperes with a frequency of up to 500 Hz in circuits with voltages ranging from 1600V to 6000V (16-32 kV). The housing type for DL153 diodes is PD53, featuring a contact surface diameter of Ø50 mm, overall dimensions of Ø75×26 mm, and a weight of 0.550 kg. “PD” stands for “pill diode,” indicating the pill-type construction.

Avalanche diodes distinguish themselves from power rectifier diodes by withstanding significant overvoltages and restoring their parameters after voltage removal. Commonly requested nominal diodes include DL153-800, DL153-1000, DL153-1250, DL153-1600, and DL153-2000.

Diodes are manufactured for operation in moderate, cold (HL), or tropical (T) climates; placement category – 2. The polarity (pinout) of the diodes is determined by the symbol on the housing. DL153 power diodes find applications as rectifying and demagnetizing diodes to prevent the detrimental effects of switching overvoltages. They are used in low-voltage rectifiers for welding and galvanic equipment, in uncontrolled or semi-controlled rectifier bridges, as well as in industrial and transportation power generators.

For efficient heat dissipation, diodes are assembled with coolers (radiators) using threaded connections. During assembly, it is crucial to ensure a reliable thermal and electrical contact between the diode and the cooler, adhering to the clamping force Fm (for DL153, the clamping force is 24±2 kN).
