Infineon BSM25GD120DN2: A 1200V, 25A IGBT Module for High-Power Industrial Drive Applications

The demand for robust and efficient power conversion in industrial environments continues to drive innovation in semiconductor technology. At the heart of many high-performance systems, such as motor drives, uninterruptible power supplies (UPS), and industrial inverters, lies the Insulated Gate Bipolar Transistor (IGBT) module. The Infineon BSM25GD120DN2 represents a prime example of this technology, engineered specifically to meet the rigorous demands of high-power industrial drive applications.

This module integrates a complete three-phase inverter bridge, featuring six IGBTs with corresponding anti-parallel diodes. Its 1200V voltage rating and 25A current capacity make it exceptionally suited for operating industrial motors and other heavy-duty equipment from common high-voltage DC bus systems. The design leverages Infineon's advanced TrenchStop™ IGBT4 technology, which is pivotal to its performance. This technology minimizes saturation voltage (Vce(sat)) and reduces switching losses, achieving an optimal balance between conduction losses and switching efficiency. The result is enhanced thermal performance and higher overall system efficiency, which is critical for reducing energy consumption and heat sink requirements in continuous operation.

Furthermore, the module is designed for reliability and ease of use. Its low-indunce design minimizes voltage overshoot during switching, enhancing system safety and protecting against voltage spikes. The soldered copper baseplate ensures excellent thermal cycling capability and reliable heat transfer to the cooling system, which is vital for maintaining performance in demanding industrial settings where ambient temperatures can be high. The module also offers a high level of integration, simplifying PCB design and reducing the bill of materials for system manufacturers.

Typical applications where the BSM25GD120DN2 excels include:

AC motor drives and controls

Industrial pumps and compressors

High-power conveyor systems

Uninterruptible Power Supplies (UPS)

Renewable energy inverter systems
