The SKM300GAR12E4 is a high-power IGBT module from SEMIKRON, rated for 300A continuous collector current and 1200V blocking voltage. Built on SEMIKRON's proven trench-gate IGBT technology, this module delivers low saturation voltage, fast switching characteristics, and robust short-circuit withstand capability. The integrated freewheeling diodes reduce external component count, and the module's isolated baseplate construction simplifies thermal management in demanding power conversion designs. It conforms to standard SEMIKRON footprint dimensions, making it a direct fit for existing drive platforms and inverter assemblies.

The SKM300GAR12E4 is well suited for medium-voltage industrial applications including AC motor drives, servo inverters, UPS systems, induction heating equipment, and renewable energy converters. Its 1200V voltage class and 300A current rating make it a reliable choice for three-phase inverter legs in industrial automation, crane and hoist drives, pump and fan variable frequency drives, and traction auxiliary systems. Engineers specifying replacements for aging drive platforms will find this module's electrical and mechanical characteristics compatible with a wide range of legacy and current-generation power stacks.

Key Features of the SKM300GAR12E4:

• 1200V collector-emitter voltage (VCES) with 300A rated collector current (IC) for high-power inverter duty
• Trench-gate IGBT cell technology providing low VCEsat for reduced conduction losses across the operating range
• Integrated co-pack freewheeling diodes with soft recovery characteristics, minimizing voltage overshoot during commutation
• Isolated copper baseplate for direct mounting to heatsink — simplifies thermal interface design and allows full module torque clamping
• Short-circuit rated per IEC 60747-9, supporting protection scheme design in industrial drive gate driver architectures
• Standard SEMIKRON SKiM/SEMITRANS-compatible footprint enabling drop-in replacement on existing PCB and busbar layouts

With a factory lead time of 42 weeks on new production, the SKM300GAR12E4 presents a real procurement challenge for maintenance teams managing unplanned downtime or OEMs building scheduled production runs. SEMIKRON's high-power modules in this current and voltage class are routinely affected by extended lead times driven by wafer allocation and substrate supply constraints. ATI Accurate Technology actively works the distributor and secondary market to locate genuine, traceable inventory for parts exactly like this one — reducing your exposure to extended outages and project delays.

ATI Accurate Technology is based in Palmetto, Florida and ships same-day on orders received before 5PM EST. We stock and source IGBTs, thyristors, diodes, and rectifier modules from leading manufacturers including SEMIKRON, with a focus on long lead time, hard-to-find, and obsolete components.
