The SEMIKRON SKT16/14C is a single-phase thyristor module engineered for demanding controlled rectifier and AC switching applications. Rated at 16A average on-state current and a 1400V repetitive peak reverse voltage (VRRM), this module is built to SEMIKRON's established SCR module platform, offering robust thermal performance through its isolated base construction and compact form factor suited for integration into standard power electronic assemblies. It is a reliable solution where high blocking voltage and controllable turn-on are required in a packaged module format.

The SKT16/14C is commonly deployed in industrial variable speed drives, soft starters, UPS systems, battery chargers, and DC power supplies where phase-controlled rectification is essential. Its isolated copper base allows direct mounting to heatsinks without additional insulation hardware, simplifying mechanical integration in motor control panels, crane and hoist drives, welding equipment, and process heating systems. Engineers specifying replacement or upgrade components in legacy industrial equipment frequently rely on this thyristor module series for its proven reliability and dimensional compatibility.

Key Features of the SKT16/14C:

• 1400V VRRM rating provides high blocking voltage margin for line-connected industrial applications operating on 380–690VAC bus systems
• 16A average on-state current (IT(AV)) supports controlled rectifier and AC controller topologies in low-to-mid power range equipment
• Isolated copper baseplate construction enables direct heatsink mounting, eliminating the need for additional insulating pads in most assemblies
• Low thermal resistance junction-to-case (RthJC) supports efficient heat dissipation in thermally constrained enclosures
• Standard SEMIKRON SKT package footprint ensures dimensional interchangeability with previous and equivalent generation SCR modules
• Gate trigger characteristics compatible with standard SCR firing boards used in phase-controlled drive platforms

The SKT16/14C carries a factory lead time of approximately 32 weeks for new production from SEMIKRON, placing it firmly in the long lead time category that challenges both MRO and OEM procurement timelines. For engineers managing aging drive platforms or facilities with planned maintenance windows, waiting on standard distribution channels is often not an option. ATI Accurate Technology actively sources hard-to-find and long lead time SEMIKRON thyristor modules through established supply channels, providing an alternative path when standard stocking distributors show extended backlog or zero inventory.

ATI Accurate Technology is based in Palmetto, Florida and stocked to support power electronics professionals who need the right part without delay. Same-day shipping is available on qualifying orders placed before 5PM EST. Whether you need a single replacement module or volume quantities for a planned outage or production run, ATI can provide competitive pricing and responsive service.
