The SEMIKRON SKKT15/12E is a dual thyristor (SCR) module in the SEMIPACK 1 package configuration, delivering a 15A average on-state current (IT(AV)) and a 1200V repetitive peak off-state voltage (VDRM/VRRM). Designed for phase-controlled power conversion, this module integrates two thyristors in a common base isolated package, simplifying assembly into heatsink-mounted power stacks. Its robust silicon construction and industry-standard footprint make it a dependable choice for demanding industrial power control circuits requiring precise, repeatable firing characteristics.

The SKKT15/12E is widely deployed across industrial automation and process control environments. Typical applications include three-phase AC motor soft starters, DC drive front-end converters, resistance heating controllers, electrochemical process power supplies, and crane or hoist drive systems. The module's isolated base allows direct mounting to a shared heatsink alongside other SEMIPACK devices, supporting compact multi-phase bridge assemblies. Its proven thyristor technology continues to be specified in new designs and as a drop-in replacement in legacy motor drive and power conditioning equipment operating in harsh industrial environments.

Quick Reference: SKKT15/12E

Key Features of the SKKT15/12E:

• Dual thyristor configuration in a single SEMIPACK 1 isolated package, reducing component count in phase-control bridge assemblies
• 1200V VDRM/VRRM blocking voltage with high dV/dt immunity for reliable operation in noisy industrial switching environments
• 15A average on-state current with low on-state voltage drop (VT), minimizing conduction losses in continuous-duty applications
• Electrically isolated copper base plate rated for direct heatsink mounting, supporting multi-device thermal management in compact power stacks
• Industry-standard SEMIPACK footprint ensures mechanical and electrical interchangeability with compatible modules from the SEMIKRON SKKT series
• Gate trigger specifications optimized for standard SCR firing boards and digital drive controllers used in motor drive and power supply platforms

With a factory lead time of approximately 34 weeks for new production, the SKKT15/12E presents a procurement challenge for maintenance teams managing unplanned downtime or engineers specifying builds with tight delivery windows. SEMIKRON thyristor modules in the SEMIPACK family are frequently required for legacy drive systems where no direct modern substitute exists. ATI Accurate Technology actively sources factory-new OEM stock of long-lead and hard-to-find SEMIKRON devices, enabling customers to bridge production gaps without compromising on part authenticity or quality.
