The SEMIKRON SKT80/16E is a SCR (silicon controlled rectifier) thyristor module designed for phase-control applications demanding reliable high-voltage switching performance. Rated at 80A average on-state current (IT(AV)) and a 1600V repetitive peak off-state voltage (VDRM/VRRM), this module is built on SEMIKRON's proven SEMIPAK platform, offering a thermally optimized copper base plate for direct heatsink mounting and consistent gate triggering characteristics across industrial operating temperature ranges.

The SKT80/16E is widely deployed in AC/DC converters, soft starters, DC motor drives, resistance heating controllers, and power supply front-end rectifier stages across industries including metals processing, plastics extrusion, crane and hoist systems, marine drives, and oil field equipment. Its robust 1600V blocking voltage class provides the necessary safety margin for 690V and 480V three-phase mains environments where voltage transients are a routine design consideration for maintenance and power electronics engineers.

Quick Reference: SKT80/16E

Key Features of the SKT80/16E:

• 80A average on-state current (IT(AV)) with high surge current capability (ITSM) for fault-tolerant system designs
• 1600V repetitive peak off-state voltage (VDRM) providing robust margin for 690V three-phase mains applications
• SEMIPAK module housing with isolated copper base plate for low thermal resistance and straightforward heatsink integration
• Low gate trigger current (IGT) and well-defined gate sensitivity for reliable firing across full temperature range
• Electrically isolated base plate rated to 2500V RMS for safe multi-module mounting configurations on shared heatsinks
• Compatible with standard SEMIKRON SEMIPAK footprint, enabling direct replacement in existing drive and converter assemblies

The SKT80/16E carries a factory lead time of approximately 35 weeks for new production from SEMIKRON, placing it firmly in the long lead time category that creates real risk for unplanned maintenance events and production line repairs. Drive systems built on legacy SEMIKRON SEMIPAK thyristor modules are common across installed industrial bases worldwide, and sourcing replacement SCR modules through distribution channels that maintain visibility into the global supply chain is critical to minimizing downtime. ATI Accurate Technology actively tracks availability on exactly these types of extended lead time and difficult-to-source power semiconductor components.

ATI Accurate Technology is located in Palmetto, Florida and stocks hard-to-find, long lead time, and obsolete power semiconductors including SEMIKRON thyristor modules.
