The SEMIKRON SKKH92/08E is a thyristor/diode combination module rated for 92A average current and 800V repetitive peak off-state voltage (V_DRM/V_RRM). Housed in SEMIKRON's industry-standard SKKH package with an isolated copper baseplate, this module integrates one phase-control SCR and one fast-recovery diode in a compact, thermally efficient assembly. It is engineered for demanding line-commutated converter and phase-control applications where reliability, thermal performance, and consistent gate triggering characteristics are non-negotiable requirements.

The SKKH92/08E is well-suited for AC/DC converters, DC motor drives, soft starters, battery chargers, welding power supplies, and industrial heating systems. Its half-controlled bridge topology makes it a go-to solution for engineers designing or retrofitting three-phase controlled rectifier stages in steel mills, oil and gas equipment, crane drives, and process automation systems. The isolated baseplate simplifies heatsink integration and allows multiple modules to share a common heatsink without additional isolation hardware, reducing assembly complexity in OEM and MRO applications alike.

Key Features of the SKKH92/08E:

• 92A average on-state current (I_TAV) with 800V V_DRM/V_RRM blocking voltage for robust medium-power phase-control use
• Integrated thyristor and fast-recovery diode in a single module, reducing component count and PCB footprint in converter assemblies
li>Isolated copper baseplate construction enables direct heatsink mounting and shared thermal management across multi-module configurations
• Low thermal resistance junction-to-case (R_th(j-c)) ensures stable operation at full rated current under continuous industrial duty cycles
• SEMIKRON SKKH package footprint is industry-standard, providing drop-in compatibility with existing PCB layouts and heatsink designs
• Gate trigger characteristics optimized for phase-control firing circuits operating across standard industrial temperature ranges

With a factory lead time of 99 weeks for new production, the SKKH92/08E represents exactly the kind of long lead-time, supply-constrained component that can bring a production line or repair project to a halt. Whether you're maintaining legacy drive systems, supporting OEM production, or stockpiling critical spares, waiting nearly two years for factory delivery is not a viable option. ATI Accurate Technology maintains an active sourcing network specifically for hard-to-find SEMIKRON modules, enabling us to locate verified new OEM inventory when factory channels are backed up or closed out entirely.

ATI Accurate Technology is located in Palmetto, Florida and ships same-day on orders placed before 5PM EST. We supply maintenance engineers, MRO buyers, and OEM procurement teams with IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long lead-time parts.
