The SEMIKRON SKT340/14E is a high-current SCR (thyristor) module engineered for phase control, soft starters, DC motor drives, and industrial rectifier systems requiring dependable switching at elevated power levels. Rated at 340A average on-state current (IT(AV)) and a 1400V repetitive peak off-state voltage (VDRM/VRRM), this module is packaged in SEMIKRON's industry-standard SKT housing, which provides an isolated baseplate for simplified heatsink mounting and straightforward integration into existing drive and converter assemblies.

The SKT340/14E is widely deployed across heavy industrial environments where robust, controllable AC-to-DC power conversion is essential. Typical applications include DC motor speed controllers, crane and hoist drives, resistance welding equipment, electrochemical power supplies, UPS input stages, and large-scale heating control systems. Its high current and voltage ratings make it well suited for steel mill auxiliary drives, mining equipment, and marine propulsion control systems where thermal stress and surge current demands are severe and component reliability is non-negotiable.

Quick Reference: SKT340/14E

Key Features of the SKT340/14E:

• 340A average on-state current (IT(AV)) with high surge current capability (ITSM) for demanding load conditions
• 1400V VDRM/VRRM repetitive peak voltage rating providing adequate margin in 690V AC line applications
• Isolated copper baseplate construction enabling direct mounting to heatsink without additional isolation hardware
• Low on-state voltage drop (VT) minimizing conduction losses and reducing thermal management requirements at full load
• Gate trigger specifications optimized for compatibility with standard SCR firing boards and digital drive controllers
• SKT industry-standard footprint ensuring form-fit-function interchangeability with equivalent modules from other SEMIKRON SKT series variants

With a factory lead time of approximately 41 weeks for new production, the SKT340/14E presents a significant procurement challenge for maintenance teams managing unplanned equipment failures or project timelines that cannot absorb that delay. ATI Accurate Technology proactively sources long lead time and allocation-status SEMIKRON thyristor modules, maintaining relationships with distribution channels that allow us to locate inventory that standard distribution cannot readily supply. If you are evaluating alternatives or need a cross-reference to a stocked equivalent, our technical team can assist. Early engagement is strongly advised given current semiconductor supply conditions.

ATI Accurate Technology is headquartered in Palmetto, Florida, and ships power semiconductors same-day on orders received before 5PM EST. We stock IGBTs, thyristors, diodes, and rectifier modules including hard-to-find and obsolete parts. Volume pricing is available for OEM and MRO procurement.
