The SEMIKRON SKT1000/16E is a screw-terminal thyristor module rated for 1000A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard SKT power package, this device is engineered for high-power phase control, soft-start, and rectification duties where long-term reliability under thermal cycling and high surge currents is non-negotiable. Its isolated copper baseplate and optimized silicon technology make it a go-to solution for engineers specifying industrial drives and converter infrastructure.

The SKT1000/16E is widely deployed in medium-voltage DC drives, thyristor-controlled rectifiers, AC power regulators, electrochemical process equipment, induction heating systems, and crane and hoist drive controllers. Utility-scale UPS systems, mine hoists, steel mill auxiliary drives, and marine propulsion converters also rely on this class of device. Wherever a rugged, high-current thyristor module must handle sustained load with minimal gate drive complexity, the SKT1000/16E is a proven incumbent component.

Key Features of the SKT1000/16E:

• 1000A average on-state current (IT(AV)) with high surge current (ITSM) capability for fault-tolerant system design
• 1600V VDRM/VRRM blocking voltage providing adequate margin in 690V and 1000V AC bus applications
• Isolated copper baseplate for direct mounting to heat sink or water-cooled cold plate without additional isolation hardware
• Low on-state voltage (VT) and well-characterized gate trigger specifications enabling precise phase-angle firing control
• Standard SKT module footprint ensuring drop-in compatibility with existing SEMIKRON-based converter platforms
• Designed for operation across a wide junction temperature range, supporting high ambient and limited-cooling industrial enclosures

With a factory lead time of approximately 34 weeks for new production, the SKT1000/16E falls squarely in the long-lead-time category that creates real scheduling risk for maintenance overhauls and new builds alike. Procurement teams supporting critical infrastructure cannot afford a 34-week outage window. ATI Accurate Technology actively sources hard-to-find and long-lead SEMIKRON thyristor modules through its distributor network, helping customers bridge the gap between factory lead times and operational deadlines. Contacting ATI early in the planning cycle is the best way to secure product ahead of a scheduled shutdown or emergency repair.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships same-day on orders placed before 5PM EST. We specialize in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead parts that other distributors can't deliver.
