The SKKH132/22EH4 is a thyristor/diode combination module from SEMIKRON's proven SKKH power semiconductor series. Rated at approximately 130A average on-state current and 2200V repetitive peak off-state voltage, this module is engineered for high-reliability phase control, soft-start, and rectification circuits where a compact, thermally efficient half-controlled bridge configuration is required. The isolated copper base plate and industry-standard footprint simplify integration into existing drive and converter assemblies, making it a direct replacement choice for field maintenance teams.

The SKKH132/22EH4 is widely deployed in industrial AC/DC converters, DC motor speed controllers, crane and hoist drives, rolling mill drives, electrochemical rectifiers, and UPS input stage circuits. Its robust construction handles the repetitive surge currents and transient overvoltages common in heavy industrial environments. Power electronics engineers specify the SKKH series for applications requiring reliable phase control under continuous duty cycles, particularly in steel, mining, marine, and process automation equipment where uptime is critical and component replacement must be fast and exact.

Key Features of the SKKH132/22EH4:

• 2200V repetitive peak off-state and reverse voltage (VDRM/VRRM) for high-voltage converter compatibility
• 130A average on-state current rating suitable for continuous industrial duty applications
• Thyristor/diode half-controlled bridge configuration in a single isolated module package
• Isolated copper base plate for direct heatsink mounting with low thermal resistance
• SKKH industry-standard footprint enabling drop-in replacement across multiple drive platforms
• Gate trigger characteristics optimized for phase-control firing circuits in motor and rectifier applications

With a factory lead time of 99 weeks on new production, the SKKH132/22EH4 presents a serious procurement challenge for maintenance teams facing unplanned equipment downtime or scheduled overhauls. SEMIKRON's long-lead SKKH modules are increasingly difficult to source through standard distribution channels on short notice. ATI Accurate Technology maintains an active network for hard-to-find, long-lead-time, and allocated power semiconductors, giving procurement professionals an alternative path to securing critical components without waiting out near-two-year factory queues. Contact ATI early to check current inventory and avoid production shutdowns.
