The SEMIKRON SKKT106/16E is a dual thyristor (SCR) module in the SEMIPACK series, rated for 106A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Built around two series-connected or independently configured SCR elements, this module is engineered for demanding phase-control, AC power regulation, and soft-start applications where high blocking voltage and reliable thermal performance are critical. The isolated copper base plate and industry-standard footprint allow direct integration into existing SEMIKRON-compatible drive platforms without mechanical redesign.

The SKKT106/16E is widely deployed in industrial AC motor drives, resistance heating controllers, thyristor power controllers, crane and hoist drives, and DC motor field excitation systems. It is equally at home in electrochemical rectifier stacks, UPS front-end converters, and renewable energy integration equipment where robust phase-control capability at medium voltage is required. OEMs and MRO teams maintaining legacy Siemens, ABB, and custom drive platforms routinely specify this module as a direct replacement for aging or failed thyristor assemblies in the field.

Key Features of the SKKT106/16E:

• Dual SCR configuration in a single SEMIPACK module for reduced component count and simplified gate drive circuitry
• 1600V VDRM/VRRM blocking voltage providing substantial safety margin in 690V and 480V AC line applications
106A IT(AV) continuous current rating with high surge current capability (ITSM) suitable for fault-tolerant designs
• Electrically isolated AlO₃ ceramic base plate enabling direct heatsink mounting without additional isolation hardware
• Industry-standard SEMIPACK footprint ensuring mechanical and electrical interchangeability with existing SEMIKRON and compatible third-party drive platforms
• Low thermal resistance junction-to-case (Rthjc) for efficient heat dissipation in high duty-cycle phase-control operation

The SKKT106/16E carries a factory lead time of approximately 41 weeks for new production orders — a reality that can halt critical equipment repairs or delay new builds when inventory is not secured in advance. Procurement teams supporting industrial plants, OEM production lines, or service depots cannot afford to rely solely on factory pipelines for a part this integral to drive reliability. ATI Accurate Technology actively maintains sourcing channels for long lead time and allocated SEMIKRON product, and we recommend reaching out early to confirm availability before your shutdown window arrives.
