The SEMIKRON SKB72/16 is a single-phase diode bridge rectifier module engineered for high-reliability AC-to-DC rectification in industrial power electronics. Built on SEMIKRON's proven SKB platform, this module integrates a full-bridge diode configuration in a compact, isolated base package suitable for demanding continuous-duty environments. With a 1600V voltage rating and 72A current capability, the SKB72/16 is a workhorse component in systems requiring stable, low-ripple DC bus generation from single-phase AC inputs. Its robust thermal design and isolated mounting base simplify heatsink integration and system assembly.

The SKB72/16 sees broad deployment across industrial and commercial power conversion applications. Common use cases include AC variable-speed drive front-ends, uninterruptible power supplies (UPS), welding power supplies, battery chargers, DC motor drive input stages, and industrial power conditioning equipment. Its voltage and current ratings make it well-suited for machinery operating on 480V single-phase mains where a rugged, field-proven bridge rectifier is required. OEM equipment manufacturers and MRO maintenance teams alike rely on this module to maintain uptime in critical production assets.

Quick Reference: SKB72/16

Key Features of the SKB72/16:

• Full single-phase diode bridge configuration in a single integrated module package
• 1600V repetitive peak reverse voltage (VRRM) for margin in high-line and transient-heavy applications
• 72A average output current (ITAV) for continuous industrial duty cycles
• Isolated copper baseplate for direct heatsink mounting without additional insulation hardware
• Low forward voltage drop diodes minimizing conduction losses and reducing thermal load
• Compact SKB footprint compatible with standard SEMIKRON mounting hardware and existing drive designs

The SKB72/16 carries a factory lead time of approximately 38 weeks for new production, placing it firmly in the long lead time category that challenges maintenance schedules and OEM production lines alike. For engineers managing aging drive systems or procurement teams building safety stock, waiting nearly ten months for a single rectifier module is operationally unacceptable. ATI Accurate Technology actively sources hard-to-find and long lead time SEMIKRON components through established distributor and broker networks, working to locate verified new OEM inventory faster than standard factory channels. Reach out early — do not wait for a failure event to start the sourcing process.
