The SEMIKRON SKR130/18 is a single-phase control thyristor (SCR) module rated for 130A average on-state current and an 1800V repetitive peak off-state voltage (VDRM/VRRM). Housed in SEMIKRON's industry-standard power module package, the SKR130/18 integrates a single thyristor element with isolated baseplate construction, simplifying heatsink mounting and system assembly. This device is engineered for controlled rectification, AC power regulation, and phase-angle firing applications where high blocking voltage and reliable gate triggering are critical to system integrity and uptime.

The SKR130/18 sees widespread deployment across heavy industrial infrastructure. Typical applications include DC motor drive front-ends, electrochemical and electrolytic process rectifiers, resistance welding controllers, crane and hoist drives, UPS input stages, and soft-start assemblies for large AC motors. Its 1800V voltage class provides essential headroom in 690V and higher distribution systems where line transients and commutation spikes demand robust off-state blocking capability. Power conversion OEMs and plant maintenance teams rely on this series for long-service-life installations in steel mills, mining equipment, chemical processing, and utility power conditioning systems.

Quick Reference: SKR130/18

Key Features of the SKR130/18:

• 1800V repetitive peak off-state voltage (VDRM) provides high transient immunity in 690V-class distribution systems
• 130A average on-state current (IT(AV)) supports continuous high-power phase-control and rectifier duty cycles
• Isolated copper baseplate for direct heatsink mounting, minimizing thermal resistance and simplifying drive enclosure design
• Standard SEMIKRON module footprint ensures mechanical and dimensional interchangeability within the SKR product family
• Low thermal resistance junction-to-case (Rth(j-c)) supports high power density designs with conventional forced-air or liquid cooling
• Gate trigger characteristics optimized for phase-angle firing circuits with standard SCR gate drive ICs and pulse transformers

With a factory lead time of approximately 39 weeks for new production, the SKR130/18 presents a real procurement challenge for maintenance teams facing unplanned equipment failures or scheduled refurbishments. SEMIKRON's phase-control thyristor modules in higher voltage classes have historically experienced extended manufacturing queues due to substrate and wafer capacity constraints. Procurement professionals managing critical spares inventories or mid-project BOM fulfillment should engage ATI early. ATI actively tracks distributor networks, excess inventory channels, and factory allocation pipelines to locate genuine SEMIKRON product when standard lead times are unacceptable.
