The SEMIKRON SKT24/16E is a phase-control thyristor (SCR) module engineered for demanding power conversion applications requiring reliable, high-voltage switching. Rated at 24A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM), this module is built for continuous industrial duty in controlled rectifier and AC power regulation circuits. Its compact module format simplifies PCB and heatsink integration, reducing system assembly time while delivering robust thermal performance through an isolated base for direct mounting to standard heatsinks.

The SKT24/16E is widely deployed in DC motor drive front-ends, soft-start controllers, welding power supplies, UPS systems, and industrial heating regulators where phase-angle control of line voltage is required. It is equally suited for use in three-phase bridge rectifier configurations, field excitation supplies for large AC and DC machines, and power conversion stages in crane, hoist, and mill drive systems. OEM equipment manufacturers across the steel, paper, chemical, and material handling industries rely on SEMIKRON thyristor modules for their proven long-term reliability in harsh environments.

Key Features of the SKT24/16E:

• 1600V VDRM/VRRM repetitive peak off-state voltage for high-line and 690V three-phase applications with adequate voltage margin
• 24A average on-state current (IT(AV)) with high surge current capability (ITSM) suitable for fault-tolerant drive designs
• Isolated copper base plate for direct heatsink mounting without additional insulating hardware, reducing thermal resistance and assembly complexity
• Standard SEMIKRON SKT module footprint ensures drop-in compatibility with existing PCB layouts and heatsink drill patterns
• Low gate trigger current (IGT) and well-defined latching/holding current parameters support reliable firing across a wide temperature range
• Designed and qualified for phase-control duty cycle, distinguishing it from fast-switching devices and ensuring long-term reliability in 50/60Hz line-commutated circuits

With a factory lead time of approximately 29 weeks for new production, the SKT24/16E presents a genuine procurement challenge for maintenance teams managing unplanned outages or OEM manufacturers building against tight delivery schedules. SEMIKRON's SKT series modules have been in production for decades, meaning legacy equipment in the field often depends on these exact part numbers. ATI Accurate Technology maintains an active sourcing network for long-lead and hard-to-find SEMIKRON thyristor modules, giving you access to inventory that standard distribution channels cannot readily provide. Reach out early to avoid costly production delays.
