Fuji 7MBR20SA060 IGBT Module

Fuji Electric 7MBR20SA060 | Compact 7-in-1 CIB IGBT Module for Integrated Motor Control

The Fuji Electric 7MBR20SA060 is a highly integrated 600V, 20A Power Integrated Module (PIM) designed to streamline the development of low-power motion control and power conversion systems. By combining a three-phase converter bridge, a three-phase inverter bridge, and a brake chopper circuit into a single compact package, this IGBT PIM drastically reduces system complexity, shrinks PCB footprint, and accelerates assembly. It is an ideal solution for engineers designing compact servo drives, general-purpose inverters, and small-scale industrial automation equipment where efficiency and space are critical design constraints.

Technical Deep Dive: The Engineering Edge of the 7MBR20SA060

The value of the 7MBR20SA060 module extends beyond simple integration. Its performance is rooted in Fuji Electric's advanced semiconductor technology, delivering tangible benefits in real-world applications.

• Optimized Vce(sat) for High Efficiency: The inverter stage IGBTs feature a low collector-emitter saturation voltage (Vce(sat)). This characteristic is not just a datasheet number; it directly translates to lower conduction losses during operation. For a motor drive running continuously, this means less wasted energy, reduced heat generation, and the potential for a smaller, more cost-effective heatsink. The result is a cooler, more energy-efficient system with a lower total cost of ownership.
• Integrated Converter-Inverter-Brake (CIB) Topology: This module is a complete front-end and motion solution. The CIB architecture consolidates the rectifier, inverter, and dynamic braking circuits. This eliminates the need for multiple discrete components, simplifying procurement, inventory management, and PCB layout. The reduced parasitic inductance between stages also contributes to better electromagnetic compatibility (EMC) performance, shortening the design and testing cycle.

Application Scenarios: Where the 7MBR20SA060 Excels

• Compact Servo Drives: In precision robotics and CNC machinery, space is a premium. The all-in-one nature of the 7MBR20SA060 allows for an extremely dense power stage design. The integrated brake chopper effectively manages regenerative energy during rapid deceleration, ensuring precise position control and protecting the DC bus without requiring bulky external braking units.
• General-Purpose AC Motor Drives: For applications like conveyor belts, pumps, and fans up to ~2.2 kW, this module provides a robust and cost-effective core. Its thermal efficiency simplifies the cooling system design, while its high level of integration reduces assembly time and potential points of failure, enhancing overall system reliability.
• Uninterruptible Power Supplies (UPS): The module's reliable performance and low power losses are crucial for battery-backed UPS systems. Its efficiency maximizes battery runtime during a power outage, and the compact PIM form factor helps create smaller, more manageable UPS units for commercial or light industrial use.

Comparative Analysis: PIM vs. Discrete Solution

Engineers often weigh the benefits of a Power Integrated Module (PIM) like the 7MBR20SA060 against a solution built from discrete IGBTs and diodes. While a discrete approach can offer layout flexibility for unique thermal constraints, the CIB module presents compelling advantages for most low-power applications. The primary benefits are significantly reduced assembly complexity, lower parasitic inductance for improved EMC, and a pre-optimized thermal path from silicon to the heatsink. For projects where time-to-market and reliability are paramount, the integrated approach of the 7MBR20SA060 is often the superior choice.

Frequently Asked Questions (FAQ)

• What are the main gate drive considerations for the 7MBR20SA060?
  You will need a gate driver IC capable of providing proper voltage levels and current to the IGBT gates. Crucially, the high-side IGBTs in the inverter bridge require an isolated power supply and level-shifting, typically achieved using bootstrap circuits or isolated DC-DC converters, to function correctly.
• How does the built-in NTC thermistor add value?
  The integrated Negative Temperature Coefficient (NTC) thermistor provides a direct, real-time method for monitoring the module's substrate temperature. This feedback can be used by the system controller to trigger thermal warnings, implement power derating, or initiate a safe shutdown, significantly enhancing the system's long-term reliability and preventing catastrophic failure from overheating.
• Can this module be used without the brake chopper?
  Yes. If your application does not involve significant regenerative energy (e.g., a simple fan or pump drive), you can simply leave the brake chopper's gate terminal disconnected and do not need to connect a braking resistor. This flexibility makes the module versatile across various application needs.
