The SEMIKRON SKT160/12E is a single SCR (thyristor) power module rated for 160A average on-state current (IT(AV)) and a 1200V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKT package with isolated baseplate, the SKT160/12E is engineered for phase-controlled rectification, AC power regulation, and motor soft-start circuits where high current handling, thermal efficiency, and long-term reliability under continuous load are non-negotiable requirements.

The SKT160/12E sees broad deployment across industrial AC and DC drive systems, medium-voltage soft starters, resistance heating controllers, crane and hoist drive controls, and field excitation circuits for large synchronous motors. Its isolated copper baseplate mounts directly to a heatsink for efficient thermal management, making it well-suited to retrofit and OEM applications in steel mills, paper mills, mining equipment, and oil and gas processing infrastructure where uptime is critical and component failure carries significant cost penalties.

Quick Reference: SKT160/12E

Key Features of the SKT160/12E:

• 160A average on-state current (IT(AV)) with high surge current (ITSM) capability for robust fault tolerance in high-demand circuits
• 1200V VDRM/VRRM repetitive peak voltage rating, suitable for 480V–690V three-phase industrial power systems
• Isolated copper baseplate construction for direct heatsink mounting, minimizing thermal resistance and simplifying mechanical integration
• Low on-state voltage drop (VT) reduces conduction losses and heat generation in continuous phase-control operation
• Gate-controlled turn-on with well-defined trigger characteristics for compatibility with standard SCR firing boards and control systems
• SEMIKRON SKT form factor ensures drop-in dimensional compatibility with existing SKT-series installations for simplified maintenance replacement

With a factory lead time of approximately 35 weeks for new production, the SKT160/12E presents a genuine procurement challenge for maintenance teams facing unplanned equipment downtime or scheduled refurbishment projects. SEMIKRON thyristor modules in this current and voltage class are frequently required to keep legacy drive systems and power controllers operational well beyond their original design service life. Waiting on factory lead times is often not an option. ATI specializes in locating and supplying exactly these types of constrained, long-lead-time, and hard-to-find power semiconductor components — sourced new and OEM.
