I. Model Description
Power Model: 5SDD0760D0001 (Printed on the device body, semiconductor model)
ABB Complete Machine Material Code: 3BHL001862P0001 (Purchase / Spare Part Number, Rectifier Tube for DCS800 DC Speed Controller)
Origin: Swiss Made (Original Factory in Switzerland) Flat Ceramic Pressed Type Diode
Core Electrical Parameters Table
Parameter item Specification value
Forward average current IF 7600A (7.6kA)
Reverse repetitive peak voltage VRRM 200V
Package structure Flat disc ceramic full-press connection Hockey Puk
Cooling method Water cooling / Forced air cooling (water cooling is standard for high current)
Chip insulation withstand voltage 2500V AC
Package size Standard high-current flat type
Structural and Process Characteristics
Full press connection without soldering structure: Vacuum hydrogen welding process, low thermal resistance, long power cycle life, suitable for high-power continuous rectification
Ceramic insulation housing: Electrical isolation, shock resistance, dust resistance, suitable for industrial heavy-duty transmission
Double-sided metal press connection surface: Pressing the upper and lower end faces for heat dissipation, no pins, installed by clamping fixtures
Soft recovery diode characteristics: Small reverse recovery charge, low high-frequency rectification loss
Supporting Equipment (Main Applications)
ABB DCS800 high-power DC speed regulator (core supporting equipment, armature / excitation rectifier bridge)
High-power rectifier power supply, electrolytic plating power supply
Industrial medium-frequency heating, mine welding machine, static reactive power compensation SVC
Heavy-duty DC motor transmission in shipbuilding, rolling, papermaking, wire drawing
UPS, high-power inverter front-end rectifier unit
Spare Parts Replacement Key Points
Reference for replacement in the same series: 5SDD71B0400 (7100A/400V, higher voltage, slightly smaller current)
Installation must be accompanied by water cooling radiator + uniform pressing fixture, the pressing force must strictly follow the manual requirements, otherwise overheating and burning out
Distinguish between diodes and the same-shaped thyristors (5STP series), the two cannot be interchanged
3BHL001862P0001 is the original ABB spare part code, when purchasing, prioritize this code for matching the DCS800 complete machine
