The SEMIKRON SKD110/12 is a three-phase diode bridge rectifier module rated for 110A average output current and a 1200V repetitive peak reverse voltage (VRRM). Housed in SEMIKRON's industry-standard SKD power module package, this component integrates a full three-phase bridge configuration into a single isolated baseplate assembly. It is engineered for high-efficiency AC-to-DC rectification with low forward voltage drop, reliable thermal conductivity to heatsink, and long-term operational stability in demanding industrial environments. The SKD110/12 conforms to established SEMIKRON design standards trusted globally in power conversion infrastructure.

The SKD110/12 is widely deployed in AC variable frequency drives (VFDs), servo drive front-end rectifier stages, uninterruptible power supplies (UPS), industrial welding equipment, DC bus charging circuits, and controlled power supply units. Its 1200V blocking voltage and 110A current rating make it well-suited for 480VAC three-phase input systems common in North American and European industrial facilities. Engineers specify this module in crane and hoist drives, pump and fan controllers, machine tool spindle drives, and regenerative braking front ends where a reliable, thermally efficient rectifier bridge is critical to system uptime.

Quick Reference: SKD110/12

Key Features of the SKD110/12:

• 1200V VRRM repetitive peak reverse voltage — suitable for 480VAC three-phase industrial input with appropriate derating margin
• 110A average rectified output current (IDAV) with full three-phase bridge topology in a single module footprint
• Isolated copper baseplate construction for direct mounting to heatsink, enabling efficient junction-to-case thermal transfer
• Industry-standard SKD package with defined creepage and clearance distances compliant with IEC and UL isolation requirements
• Low forward voltage drop diodes minimize conduction losses and reduce thermal load on the heatsink assembly
• Compatible with standard SEMIKRON SKD-series mounting hardware and heatsink profiles, simplifying drop-in replacement in existing drive platforms

The SKD110/12 carries a factory lead time of approximately 33 weeks for new production orders, placing it firmly in the long-lead-time category that creates real risk for maintenance and production teams managing aging drive platforms. Procurement professionals dealing with VFD or rectifier assembly lines dependent on this module cannot afford to wait on factory build cycles when a field failure occurs. ATI Accurate Technology actively sources hard-to-find and long-lead SEMIKRON modules through authorized and vetted supply channels, providing a critical buffer against extended downtime. Engaging ATI early — before the failure occurs — is the most cost-effective strategy.
