The SEMIKRON SEMiX302GB128D is a high-power IGBT module from the well-established SEMiX platform, offering approximately 300A continuous current capability at 1200V blocking voltage. Engineered for efficiency and ruggedness, this module integrates IGBT chips with a freewheeling diode in a low-inductance, direct-bonded copper substrate package. The SEMiX platform's standardized footprint and gate-drive compatibility make it a preferred choice for design engineers working with high-power conversion equipment requiring proven reliability and consistent thermal performance across demanding duty cycles.

The SEMiX302GB128D is widely deployed in industrial AC motor drives, regenerative inverters, UPS systems, and medium-voltage power supplies. Its robust construction suits applications in steel mills, paper manufacturing, HVAC central plant equipment, oil and gas pumping systems, and renewable energy converters. OEMs and end-users relying on SEMIKRON SEMiX topology for legacy drive platforms frequently require this specific module for field repair, production continuity, or system upgrades where form-fit-function replacement is critical to minimizing downtime and avoiding costly drive cabinet redesigns.

Quick Reference: SEMiX302GB128D

Key Features of the SEMiX302GB128D:

• 1200V collector-emitter voltage (VCES) with high short-circuit ruggedness suitable for industrial converter environments
• SEMiX industry-standard package footprint enabling direct form-fit-function replacement in existing drive platforms
• Integrated freewheeling diode co-packaged with IGBT chips for reduced external component count and lower parasitic inductance
• Direct bonded copper (DBC) substrate construction for superior thermal cycling endurance and reduced junction-to-case thermal resistance
• Optimized for both hard-switching and soft-switching inverter topologies operating at medium switching frequencies (1–8 kHz range)
• Compatible with standard SEMiX gate-drive reference designs, reducing engineering effort for drop-in drive system replacements

With a factory lead time of 99 weeks on new production, the SEMiX302GB128D presents a serious procurement challenge for maintenance teams managing scheduled outages or OEMs holding build schedules. SEMIKRON's SEMiX platform modules are heavily utilized across long-lifecycle industrial equipment, meaning demand frequently outpaces factory allocation. ATI Accurate Technology actively maintains relationships with authorized distribution channels and secondary market sources to locate genuine, traceable SEMIKRON inventory. Engaging ATI early in your planning cycle is the most effective strategy for securing this module without costly production delays.

ATI Accurate Technology is based in Palmetto, Florida and specializes in exactly these scenarios—long lead time, hard-to-find, and obsolete power semiconductors including IGBTs, thyristors, diodes, and rectifier modules.
