The SEMIKRON SKT160/12C is a single thyristor (SCR) module rated at 160A average on-state current and 1200V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKT package with an isolated copper baseplate, this module is engineered for robust performance in phase-controlled rectifier and AC power controller topologies. Its well-characterized gate trigger characteristics and low thermal resistance make it a reliable choice for high-power industrial designs requiring consistent, repeatable switching behavior across extended operating cycles.

The SKT160/12C sees widespread deployment in industrial AC/DC motor drives, soft-start systems, resistance welding controllers, electrochemical process rectifiers, and crane or hoist power stages. It is also used in UPS systems, voltage regulators, and heating control equipment where precise phase-angle firing is essential. The module's isolated baseplate simplifies heatsink mounting and electrical isolation in multi-module assemblies, making it a preferred building block for three-phase bridge and antiparallel converter configurations across metals processing, paper, plastics, and heavy manufacturing sectors.

Key Features of the SKT160/12C:

• 160A average on-state current (IT(AV)) with 1200V VDRM/VRRM repetitive blocking voltage for high-power phase control circuits
• Low on-state voltage drop (VT) minimizes conduction losses and reduces heatsink thermal requirements in continuous-duty applications
• Isolated copper baseplate construction provides electrical isolation between the semiconductor die and heatsink, simplifying multi-module bus configurations
• Well-defined gate trigger current (IGT) and holding current (IH) parameters ensure consistent firing performance with standard SCR gate drive circuits
• Low thermal resistance junction-to-case (RthJC) supports efficient heat extraction in forced-air and liquid-cooled heatsink assemblies
• Compatible with industry-standard SKT package footprint, enabling direct form-fit-function replacement in existing SEMIKRON-based converter designs

With a factory production lead time of 34 weeks, the SKT160/12C presents a significant sourcing challenge for maintenance teams managing unplanned downtime or procurement teams running lean inventories. SEMIKRON thyristor modules in the SKT series are common in legacy drive and converter platforms that remain in active service well beyond original design lifecycles. ATI Accurate Technology specializes in exactly these scenarios — maintaining supplier relationships and inventory pipelines for long-lead-time, hard-to-find, and obsolete power semiconductor modules so your equipment stays running without a 34-week wait.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We specialize in IGBTs, thyristors, diodes, and rectifier modules — including the difficult parts others can't source.
