SanRex DFA100BA160 | High-Integration 1600V CIB Power Module
The SanRex DFA100BA160 is engineered not merely as a component, but as a complete power stage solution for high-voltage industrial applications. This Power Integrated Module (PIM) consolidates a three-phase diode rectifier, a three-phase IGBT inverter, and a brake chopper circuit into a single, robust package. Designed for systems demanding high reliability and power density, the DFA100BA160 is the cornerstone for developing efficient 100A, 1600V motor drives, uninterruptible power supplies (UPS), and industrial power conversion systems.
Technical Deep Dive: The CIB Advantage
The core value of the SanRex DFA100BA160 lies in its highly integrated Converter-Inverter-Brake (CIB) topology. This architecture delivers tangible engineering benefits:
- System Simplification: By integrating the AC-DC converter, DC-AC inverter, and dynamic braking circuit, this module drastically reduces external component count. This translates to a smaller PCB footprint, simplified assembly, and fewer points of potential failure.
- Minimized Parasitic Inductance: The compact internal layout minimizes stray inductance between the power stages. This is crucial for reducing voltage overshoots during high-speed switching, which simplifies snubber circuit design and improves overall electromagnetic compatibility (EMC).
- Optimized Thermal Performance: The module is built upon an Aluminum Nitride (AlN) substrate, which offers superior thermal conductivity compared to conventional alumina. This ensures efficient heat transfer from the silicon die to the heatsink, enabling higher power density and extending the operational lifetime of the entire system.
Application Scenarios & Value Proposition
The DFA100BA160 excels in applications where performance and reliability are non-negotiable:
- High-Power Motor Drives: In heavy-duty AC motor or IGBT in motor drive applications, rapid deceleration can generate significant regenerative energy. The integrated brake chopper in the DFA100BA160 provides a ready-made, robust solution for dissipating this energy, protecting the DC bus and ensuring controlled braking without complex external circuits.
- Uninterruptible Power Supplies (UPS): For online double-conversion UPS systems, this module provides the entire power conversion backbone. Its high voltage rating of 1600V offers substantial design margin for 380/400V AC line applications, enhancing the system's resilience against line voltage fluctuations.
- Industrial Automation & Welding: In robotics, servo controls, and welding equipment, space is often at a premium. The compact CIB design allows for a significant reduction in the overall size of the power electronics, while its proven reliability ensures maximum uptime in harsh factory environments.

Selection Insight: Integrated vs. Discrete
Engineers often weigh the trade-offs between a fully integrated module like the SanRex DFA100BA160 and a solution built from discrete components. While a discrete approach may offer granular component selection, it introduces significant design complexity in layout, thermal management, and sourcing. The DFA100BA160 provides a pre-validated, optimized solution that accelerates time-to-market, reduces assembly costs, and inherently improves system reliability by minimizing interconnects. It is the superior choice for projects where development speed and long-term dependability are paramount. For other system architectures, feel free to Explore More IGBT Modules in our portfolio.
Frequently Asked Questions (FAQ)
- What are the best practices for driving the gates of this module?Due to the integrated nature, it is critical to use a gate driver IC with sufficient current capability and galvanic isolation. Ensure short, low-inductance traces from the driver to the module's gate-emitter pins and use a dedicated, isolated power supply for each driver to prevent crosstalk and ensure reliable switching.
- How critical is the IGBT Vce(sat) value?Extremely critical. The low Vce(sat) of 2.1V at nominal current directly translates to lower conduction losses (Power Loss = Vce(sat) * Ic). This reduces the heat generated by the module, allowing for a smaller heatsink, or enabling operation at higher ambient temperatures, which is a significant advantage in enclosed industrial cabinets.
