The SEMIKRON SKR26/16 is a single SCR (silicon controlled rectifier) thyristor module delivering 26A average on-state current (IT(AV)) and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built in SEMIKRON's established module platform, it integrates the thyristor die with an isolated copper baseplate and industry-standard bolt-down terminals, enabling straightforward integration onto standard heatsinks. The high voltage rating makes it well suited for applications where line transients, inrush conditions, or elevated DC bus voltages demand robust blocking capability without oversizing to a larger device class.

The SKR26/16 is widely deployed in industrial AC/DC converters, soft-start motor controllers, resistance welding equipment, and DC drives where phase-controlled rectification is required. Its 1600V voltage class provides the headroom required in 690V three-phase systems after derating. The part also appears in UPS systems, field excitation circuits, battery chargers, and electrolytic process rectifiers — anywhere a reliable, gate-triggered switch must handle sustained on-state current with controlled turn-on characteristics. Replacement and retrofit applications in legacy installed base equipment represent a significant share of demand for this series.

Quick Reference: SKR26/16

Key Features of the SKR26/16:

• 1600V VDRM/VRRM repetitive peak off-state voltage — suitable for 690V three-phase line applications with standard derating margins
• 26A IT(AV) average on-state current rating with low on-state voltage drop for reduced conduction losses
• Isolated copper baseplate construction provides electrical isolation between the thyristor junction and heatsink mounting surface
• Standard gate trigger interface compatible with conventional SCR firing boards and phase-control trigger circuits
• Compact single-thyristor module format simplifies replacement in half-wave, mid-point, and series-connected converter topologies
• SEMIKRON's established SKR series platform with decades of fielded history in demanding industrial environments

Factory lead times for new production SKR26/16 units currently run approximately 35 weeks through standard distribution channels. For maintenance teams facing unplanned downtime or procurement teams managing MRO spares, that timeline is operationally unacceptable. ATI Accurate Technology specializes in exactly this gap — sourcing long-lead-time, hard-to-find, and catalog-discontinued SEMIKRON thyristor modules from verified supply channels. Whether you need a single replacement unit or buffer stock for a critical installed base, contact ATI early to confirm availability before a production stoppage forces the issue.

ATI Accurate Technology is based in Palmetto, Florida and ships same-day on orders received before 5PM EST. We supply maintenance engineers and procurement professionals with IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead-time parts.
