Key Features
- 1200 V / 20 A IGBT-based Converter-Brake-Inverter (CBI) topology integrates rectifier, braking chopper, and 3-phase inverter in a single isolated module
- Low switching loss and low VCEsat IGBT technology reduces power dissipation at switching frequencies up to 20 kHz in variable-speed motor drive applications
- Isolated case construction (JESD-30 R-XUFM-X24) with 7 internal elements eliminates external isolation components and simplifies heatsink mounting in industrial drive enclosures
Applications
The MUBW10-12A7 is designed for compact variable-speed AC motor drives, servo amplifiers, and regenerative braking systems operating from 3-phase 400 V to 600 V AC mains. Its integrated CBI topology reduces component count and PCB area in industrial drives rated up to approximately 0.75 kW to 1.5 kW output power. The isolated package simplifies thermal management by mounting directly to a heatsink without additional insulator pads.

Frequently Asked Questions
What voltage and current ratings define the MUBW10-12A7's suitability for 400 V AC motor drives?
The MUBW10-12A7 has a 1200 V collector-emitter breakdown voltage and 20 A maximum collector current, providing 2x voltage margin above the 600 V DC bus typical of 400 V AC three-phase drives. This headroom absorbs switching voltage spikes and transients without requiring additional snubber networks in drives rated up to 1.5 kW continuous output power.
How does the integrated Converter-Brake-Inverter topology of MUBW10-12A7 reduce BOM compared to discrete designs?
The CBI module integrates a 3-phase diode rectifier bridge, a braking chopper IGBT with freewheeling diode, and a 3-phase IGBT inverter bridge—totaling 7 internal power elements—into a single 24-pin isolated package. A discrete implementation of the same function would require approximately 12 to 14 separate power semiconductors plus individual gate drivers and isolation components.
At what switching frequency can the MUBW10-12A7 operate, and how does its low switching loss characteristic support this?
The MUBW10-12A7 IGBTs are optimized for switching frequencies up to 20 kHz, with low turn-on and turn-off energy loss typically below 0.5 mJ per pulse at 600 V and 10 A. This allows variable-speed motor drives to operate above the 16 kHz audible noise threshold while keeping module junction temperatures within the -40°C to 125°C rated operating range.
What heatsink mounting arrangement does the isolated case of MUBW10-12A7 allow for thermal management?
The isolated case design of the MUBW10-12A7 provides electrical isolation between the internal power circuit and the module baseplate, allowing direct mounting to a grounded aluminum heatsink without an intermediate insulator pad. This reduces thermal resistance between junction and heatsink by approximately 0.3°C/W compared to non-isolated modules using mica or silicone isolation pads.
