Infineon BSM35GP120: A High-Performance 35A IGBT Module for Industrial Drives and Power Conversion
The demand for robust, efficient, and reliable power electronics is at an all-time high, driven by the rapid advancement of industrial automation and energy conversion systems. At the heart of many of these applications lies the Insulated Gate Bipolar Transistor (IGBT) module, a critical component that switches high currents and voltages with precision. The Infineon BSM35GP120 stands out as a premier solution in this category, engineered specifically to meet the rigorous demands of modern industrial drives and power conversion equipment.
This 35A, 1200V IGBT module is built upon Infineon's proven third-generation TrenchStop™ IGBT technology. This advanced cell design significantly enhances performance by reducing saturation voltage (VCE(sat)) and minimizing switching losses. The result is a remarkable improvement in overall efficiency, which is paramount for reducing thermal stress and energy consumption in continuous-operation systems like motor drives and uninterruptible power supplies (UPS).
A key feature of the BSM35GP120 is its low-loss and soft-recovery diode co-packaged with the IGBT. This anti-parallel emitter-controlled diode is optimized for minimal reverse recovery current, which is crucial for suppressing voltage overshoots and electromagnetic interference (EMI). This leads to smoother switching transitions, enhanced system reliability, and a reduction in the need for external snubber circuits, thereby simplifying design and lowering overall system cost.
The module is designed for high power density and easy integration. Its compact and robust transfer molded package ensures high mechanical stability and excellent isolation properties. The baseplate is optimized for thermal performance, allowing for effective heat dissipation when mounted on a heatsink. This design is essential for maintaining junction temperatures within safe operating limits, even under high load conditions in industrial environments.
Furthermore, the BSM35GP120 offers superior short-circuit ruggedness (tsc = 10µs), providing a critical safety margin in fault conditions common in industrial settings. This ruggedness, combined with a wide operating junction temperature range (Tvj = -40 °C to +150 °C), ensures long-term operational stability and durability, minimizing downtime and maintenance costs.
Typical applications where this module excels include:
AC motor drives and servo controllers
Industrial inverters and welding equipment
Power supplies and UPS systems
Renewable energy inverters
ICGOO
In summary, the Infineon BSM35GP120 is a high-performance IGBT module that delivers an optimal balance of efficiency, reliability, and power density. Its advanced TrenchStop™ technology, integrated soft-recovery diode, and rugged construction make it an exceptional choice for engineers designing next-generation industrial drives and power conversion systems.
