The SEMIKRON SKR100/16 is a thyristor (SCR) power module delivering 100A average on-state current and a 1600V repetitive peak off-state voltage (V_DRM/V_RRM). Built to SEMIKRON's established module construction standards, it features an isolated copper base plate, low thermal resistance, and reliable gate triggering characteristics. This module is engineered for high-reliability phase-control circuits where consistent forward voltage drop, rugged blocking capability, and thermal performance are non-negotiable requirements in demanding industrial environments.

The SKR100/16 is widely deployed in DC motor drives, soft-start units, AC power controllers, resistance welding equipment, electrochemical rectifiers, and industrial heating systems. Its 1600V voltage class makes it a preferred choice for 690V AC line applications where designers require adequate voltage margin against transients and surge events. The module is equally at home in retrofit and MRO scenarios as it is in original equipment, supporting applications across steel, paper, mining, marine, and process automation industries.

Quick Reference: SKR100/16

Key Features of the SKR100/16:

• 1600V repetitive peak off-state voltage providing robust transient margin on 480V–690V AC systems
• 100A average on-state current (I_TAV) with low forward voltage drop for reduced conduction losses
• Isolated base plate construction for direct heatsink mounting without supplemental isolation hardware
• Low thermal resistance junction-to-case (R_th(j-c)) enabling high power density in compact drive enclosures
• Gate triggering parameters optimized for standard SCR firing cards and gate drive circuits
• SEMIKRON SEMIPAK module form factor ensuring dimensional interchangeability with existing platform designs

New production of the SKR100/16 carries a factory lead time of 99 weeks — well beyond the tolerance of most maintenance and production schedules. For facilities running phase-control drives or power controllers built around this part, an unplanned failure without a stocked replacement can mean extended downtime and costly production losses. ATI Accurate Technology maintains inventory of the SKR100/16 precisely for these situations, serving OEM service departments, MRO procurement teams, and engineering firms that cannot afford to wait out manufacturer lead times.
