Basic Description
- The SKIIP11NAB12T4V1 is a power semiconductor module combining a 3-phase bridge inverter, input rectifier, and brake chopper in one package.
- It is part of SEMIKRON’s MiniSKiiP family.
- It contains 4 IGBTs (trench technology) and associated freewheeling diodes, plus the supporting circuits.
- It is intended for inverter applications up to about 8 kVA rating, e.g., driving motors up to about 4 kW under typical conditions.
