The SEMIKRON SKDH115/16 is a three-phase diode bridge rectifier module rated for 115A average output current and 1600V repetitive peak reverse voltage. Built on SEMIKRON's proven SKD platform with an integrated bypass diode configuration, this module delivers efficient, low-ripple AC-to-DC rectification in a compact, thermally optimized package. Its robust construction — featuring a copper baseplate for superior heat spreading and industry-standard mounting footprint — makes it a reliable choice for engineers designing or maintaining high-power industrial conversion equipment where thermal performance and long service life are non-negotiable.

The SKDH115/16 is widely deployed across heavy industrial sectors including variable frequency drives (VFDs), DC motor drives, industrial UPS systems, welding equipment, soft starters, and regenerative braking units. Its 1600V blocking voltage provides the necessary margin for 690VAC three-phase line inputs after accounting for transient overvoltages, making it particularly well-suited for European and international medium-voltage industrial environments. Energy infrastructure equipment, elevator drive systems, crane controls, and machine tool spindle drives also commonly rely on this module for front-end rectification in multi-kilowatt power stages.

Key Features of the SKDH115/16:

• 1600V V_RRM rating provides full voltage margin on 690VAC three-phase inputs with transient headroom
• 115A average output current (I_DAV) supports multi-kilowatt drive and rectifier front-end stages
• Integrated three-phase bridge topology with bypass diode simplifies PCB and busbar layout
• Copper baseplate construction enables low thermal resistance to heatsink for high-duty-cycle operation
• Industry-standard SKD footprint ensures direct form-fit-function replacement compatibility with installed base equipment
• UL-recognized, RoHS-compliant construction meeting international industrial certification requirements

With a factory lead time of 99 weeks on new production, the SKDH115/16 presents a serious procurement challenge for MRO buyers, OEM service teams, and system integrators who cannot afford extended downtime. SEMIKRON's SKD-series modules are deeply embedded in global installed base equipment, and replacement demand consistently outpaces new production allocations. ATI Accurate Technology maintains active sourcing channels for exactly these situations — tracking distributor inventory, factory allocation windows, and certified aftermarket supply to get qualified stock into your hands when the standard supply chain cannot deliver.

ATI Accurate Technology is headquartered in Palmetto, Florida, and stocks a broad range of SEMIKRON and complementary power semiconductor modules. Orders placed before 5PM EST ship same day.
