The SEMIKRON SKD115/16 is a three-phase diode bridge rectifier module engineered for high-power AC-to-DC conversion in industrial drive systems, UPS units, and heavy-duty power supply designs. Built to SEMIKRON's established construction standards, this module integrates multiple rectifier diodes into a compact, thermally efficient package that simplifies board layout and reduces assembly complexity. The SKD115/16 is intended for applications where reliability under continuous load, thermal cycling, and high ambient temperatures is non-negotiable — making it a trusted component in industrial power electronics worldwide.

The SKD115/16 sees broad deployment across industrial motor drives, crane and hoist control systems, welding power supplies, regenerative braking systems, and large UPS installations. Its three-phase bridge topology makes it well-suited for converting utility AC input to a stable DC bus in variable frequency drives (VFDs) and servo amplifier front-ends. Engineers specify this module in applications requiring consistent rectification performance over extended service intervals, particularly in process automation, material handling, marine power systems, and energy generation equipment where downtime carries significant operational cost.

Quick Reference: SKD115/16

Key Features of the SKD115/16:

• Three-phase bridge rectifier configuration for full-wave AC-to-DC conversion with low ripple output
• 115 A average output current rating suitable for high-current industrial drive front-ends
• 1600 V repetitive peak reverse voltage (VRRM) providing robust margin in 690 V AC line environments
• Isolated baseplate construction enabling direct heatsink mounting without additional insulation hardware
• Low forward voltage drop across rectifier elements minimizes conduction losses and thermal stress at rated current
• Compact SKD package footprint reduces PCB and busbar real estate while maintaining high power density

The SKD115/16 carries a factory lead time of approximately 37 weeks for new production, a reality increasingly common across the SEMIKRON rectifier module portfolio as global semiconductor supply chains remain constrained. For maintenance engineers managing aging drive systems or procurement teams building safety stock, waiting nearly a year for replacement modules is not operationally viable. ATI Accurate Technology actively sources long-lead-time and allocation-constrained SEMIKRON components through established distributor and secondary-market channels, helping customers secure verified, new-condition inventory ahead of critical project deadlines or unplanned equipment failures.

ATI Accurate Technology is headquartered in Palmetto, Florida, and stocks a broad range of IGBT modules, thyristors, diodes, and rectifier modules from leading manufacturers including SEMIKRON.
