The SEMIKRON SKT100/16E is a 100-ampere, 1600-volt SCR (silicon controlled rectifier) thyristor module engineered for high-power phase control and rectification applications. Housed in SEMIKRON's industry-standard SKT package, this module integrates a single thyristor die with an isolated baseplate for direct heatsink mounting, simplifying thermal management in dense power assemblies. The 1600V voltage class provides ample blocking margin for line-connected applications operating from 480V to 690V three-phase mains, making it a dependable choice where voltage transients and surge conditions are a design concern.

The SKT100/16E is widely specified in industrial AC motor soft starters, DC drive converters, resistance welding controllers, crane and hoist drives, UPS rectifier stages, and electrochemical process power supplies. Its combination of high repetitive peak off-state voltage (VDRM/VRRM 1600V) and 100A average on-state current suits multi-pulse bridge topologies common in heavy industrial equipment. OEM drive manufacturers and MRO procurement teams routinely specify this module as a replacement or upgrade component in legacy systems originally designed around the SEMIKRON SKT family.

Quick Reference: SKT100/16E

Key Features of the SKT100/16E:

• 1600V repetitive peak off-state and reverse voltage (VDRM/VRRM) for robust margin on high-line 690V systems
• 100A average on-state current (IT(AV)) rated at 180° conduction angle with heatsink-mounted baseplate
• Low thermal resistance junction-to-case (RthJC) enabling efficient heat transfer to standard SKT-compatible heatsink profiles
• Isolated copper baseplate construction for electrical isolation between the power circuit and heatsink/chassis
• Gate trigger current (IGT) and holding current (IH) optimized for reliable firing from standard SCR gate driver circuits
• Compact SKT module footprint compatible with existing PCB and busbar layouts designed around the SEMIKRON SKT100 series

The SKT100/16E carries a factory lead time of approximately 31 weeks for new production orders — a reality increasingly common across SEMIKRON's thyristor module portfolio as semiconductor fabrication capacity remains constrained. For maintenance teams facing unplanned downtime or procurement professionals building safety stock, a 31-week wait is operationally unacceptable. ATI Accurate Technology actively sources long-lead and allocated SEMIKRON components through authorized and verified distribution channels, helping customers bridge the gap between factory lead times and production or repair schedules. Contact ATI early to discuss buffer stock strategies and allocation options.
