The SEMIKRON SK70D16 is a high-voltage IGBT module rated at 70 amperes and 1600 volts, engineered for applications where elevated DC bus voltages and robust switching characteristics are non-negotiable. SEMIKRON's module construction integrates the IGBT chip and freewheeling diode within a compact, industry-standard housing, delivering low saturation voltage, controlled di/dt turn-off behavior, and thermal performance suited to continuous duty cycles in harsh industrial environments. The SK70D16's 1600V voltage class makes it a preferred solution wherever standard 1200V devices lack the margin required by application safety standards.

The SK70D16 sees deployment across a broad range of industrial and energy power electronics platforms. Common applications include medium-voltage AC motor drives, regenerative braking systems, UPS inverter stages, induction heating equipment, and grid-tied renewable energy converters where 1600V blocking capability provides necessary headroom above rectified mains voltages. It is also well suited for traction auxiliary converters and industrial welding inverters that demand consistent gate-drive compatibility and predictable thermal impedance across the module's operational lifetime.

Quick Reference: SK70D16

Key Features of the SK70D16:

• 1600V collector-emitter blocking voltage providing robust margin for high-line and medium-voltage bus applications
• 70A continuous collector current rating suitable for kilowatt-class inverter and drive stages
• Integrated co-pack freewheeling diode optimized for low reverse recovery charge (Qrr) in hard-switching topologies
• Low VCE(sat) characteristic minimizes conduction losses and reduces heatsink thermal requirements at rated current
• Industry-standard module footprint and pinout ensuring drop-in compatibility with existing SEMIKRON-based drive platforms
• Isolated baseplate construction supporting direct mounting to heatsink with standard thermal interface materials

The SK70D16 carries a factory lead time of approximately 39 weeks for new production, placing it firmly in the long lead time category that routinely disrupts MRO and capital project schedules. Procurement teams managing installed base equipment built around SEMIKRON's older module families know the challenge: OEM build schedules don't wait for semiconductor lead times. ATI maintains active sourcing channels for exactly these situations, working to locate verified new OEM inventory from distributor networks and factory-authorized sources to close the gap between your need date and factory availability.
