The Semikron SKN100/16 is a screw-terminal thyristor (SCR) module rated for 100A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in Semikron's compact, industry-standard SKN package, this module integrates isolated base mounting for simplified heatsink assembly and reduced system wiring complexity. It is engineered for continuous duty in phase-controlled rectification, soft-start circuits, and AC power regulation where high blocking voltage and reliable gate sensitivity are critical design requirements.

The SKN100/16 is widely deployed across demanding industrial environments including DC motor drives, resistance welding controllers, electrochemical power supplies, UPS systems, and crane and hoist drive platforms. Its robust voltage rating makes it particularly well suited for 690VAC three-phase input topologies where transient overvoltages demand substantial margin. Utility and process industries rely on this class of thyristor module in furnace controls, transformer tap changers, and high-current battery chargers where long service life and stable triggering characteristics are non-negotiable.

Quick Reference: SKN100/16

Key Features of the SKN100/16:

• 1600V VDRM/VRRM repetitive peak blocking voltage for high-line and 690VAC three-phase applications
• 100A IT(AV) average on-state current rating with low on-state voltage drop for efficient thermal management
• Isolated copper base plate provides electrical isolation between die and heatsink, simplifying mounting in multi-module assemblies
• Standard SKN screw-terminal package ensures direct interchangeability with equivalent modules from compatible manufacturers
• High di/dt and dv/dt capability supports demanding phase-control firing angles and snubberless designs in many topologies
• Gate trigger characteristics optimized for compatibility with standard SCR firing boards and pulse transformer drivers

With a factory lead time currently exceeding 99 weeks for new production, the SKN100/16 represents exactly the kind of long-lead-time component that can stall a critical repair or new build. Semikron's SKN-series thyristor modules are deeply embedded in legacy drive platforms and industrial equipment with 20-plus year service lives, meaning demand persists well beyond standard production cycles. Procurement teams sourcing this part for MRO inventory, OEM production continuity, or emergency field replacement need a distributor with active market intelligence and access to genuine, traceable new OEM stock — not gray-market substitutes.
