The SEMIKRON SKB60/18 is a single-phase diode bridge rectifier module combining four rectifier diodes in a standard B-configuration package. Rated at 60A continuous forward current and 1800V repetitive peak reverse voltage (VRRM), this module is engineered for demanding AC-to-DC rectification tasks where high blocking voltage and reliable thermal management are non-negotiable. The integrated module format reduces assembly complexity, improves thermal contact to heatsinks, and minimizes parasitic inductance compared to discrete component assemblies, making it a preferred solution in high-reliability industrial designs.

The SKB60/18 is well-suited for industrial drives, UPS systems, welding equipment, field excitation circuits, and DC power supplies operating from medium-voltage AC mains. Its 1800V voltage class provides the necessary margin for line transients in 690V and higher AC input environments. Power conversion engineers also specify this module in regenerative drive front ends, elevator drive systems, crane and hoist controls, and industrial battery charging infrastructure where continuous duty rectification under variable load is a primary design requirement.

Key Features of the SKB60/18:

• 1800V VRRM rating provides substantial voltage headroom for 690VAC three-phase input applications and line transient protection
• 60A average forward current (IFAV) supports continuous duty rectification in industrial power conversion equipment
• B-configuration single-phase bridge topology integrates four diodes in one compact, heatsink-mountable module
• Electrically isolated baseplate enables direct mounting to a common heatsink without additional insulation hardware
• Standard SEMIKRON module footprint ensures drop-in compatibility with existing PCB and heatsink designs using legacy SKB-series layouts
• Low forward voltage drop minimizes conduction losses, reducing thermal stress and improving overall system efficiency at rated current

The SKB60/18 carries a factory lead time of approximately 36 weeks for new production orders, placing it firmly in the long-lead-time category that challenges maintenance schedules and MRO procurement alike. For OEMs managing end-of-life equipment or facilities maintaining aging industrial drives, sourcing this module through open-market distribution channels is often the only practical path to avoiding extended downtime. ATI Accurate Technology specializes in exactly this scenario — tracking down SEMIKRON bridge modules that standard distribution channels cannot readily fulfill and providing verified new OEM product from trusted supply chain sources.

ATI Accurate Technology is located in Palmetto, Florida, and stocks power semiconductors including diode bridge modules, IGBTs, thyristors, and rectifier assemblies from leading manufacturers. Orders placed before 5PM EST ship same day. Whether you need a single replacement module or volume pricing for a scheduled maintenance program, our team is ready to help.
