The SEMIKRON SKB25/16 is a single-phase bridge rectifier module combining four diodes in a compact, isolated case package. Rated for a 25A average output current and a peak repetitive reverse voltage of 1600V, this module is engineered for demanding AC-to-DC rectification tasks where voltage headroom and thermal reliability are critical. The isolated baseplate construction allows direct heatsink mounting, reducing system component count and simplifying thermal management in space-constrained control cabinets and power assemblies.

The SKB25/16 sees widespread deployment across industrial variable-speed drives, DC power supplies, welding equipment, UPS systems, and field excitation circuits in motors and generators. Its 1600V blocking voltage rating makes it well-suited for 690V AC line inputs and applications where line transients demand elevated voltage margin. The module is also found in soft-start controllers, battery chargers, elevator drives, and crane control systems — anywhere a reliable, thermally manageable bridge rectifier is required in a production-grade package.

Quick Reference: SKB25/16

Key Features of the SKB25/16:

• 1600V repetitive peak reverse voltage (V_RRM) providing substantial margin for 480V and 690V AC input systems
• 25A average forward current (I_FAV) with low forward voltage drop for efficient rectification and reduced conduction losses
• Isolated copper baseplate for direct heatsink mounting, enabling effective thermal dissipation without additional insulation pads in most configurations
• Single-phase full-wave bridge topology in a single module — eliminates discrete diode assembly, reduces wiring complexity and assembly time
• SEMIKRON SKB package with industry-standard footprint, simplifying drop-in replacement in existing board and chassis designs
• Qualified for continuous industrial duty across a wide operating temperature range, consistent with SEMIKRON's production-grade manufacturing standards

The SKB25/16 carries a factory lead time of approximately 38 weeks for new production orders, a reality driven by ongoing semiconductor supply constraints affecting power module manufacturing globally. For maintenance operations or OEM production lines that cannot tolerate a 9-month wait, sourcing from a distributor with access to allocated stock, excess inventory channels, or manufacturer pull-forward agreements is essential. ATI Accurate Technology maintains active sourcing relationships and inventory pipelines specifically for long-lead-time SEMIKRON modules, giving procurement teams a practical alternative to extended factory queues.

ATI Accurate Technology is headquartered in Palmetto, Florida, and stocks power semiconductors for customers across North America and internationally.
