EUPEC BSM300GA120DN2S High-Power IGBT Switching Module – FF Series (Full-Bridge)
When a high-power IGBT module fails on the production floor, the consequences are immediate and severe: drive systems shut down, conveyor lines halt, and entire manufacturing cells go dark. In high-demand applications such as medium-voltage drives, industrial UPS systems, and traction inverters, even minutes of unplanned downtime translate into significant financial loss. The EUPEC BSM300GA120DN2S is the precision-engineered component that keeps these critical systems running — a 300A, 1200V full-bridge IGBT power module built to withstand the thermal and electrical stresses of continuous industrial operation.
Within the EUPEC FF Series, the BSM300GA120DN2S occupies a high-current, medium-voltage tier that makes it the preferred choice for engineers designing or maintaining 3-phase inverter stages, regenerative drives, and active front-end rectifiers. EUPEC (now part of Infineon Technologies) has long been recognized as a global benchmark for IGBT module reliability, and the BSM300GA120DN2S continues that legacy — combining low saturation voltage (VCE(sat)), fast switching characteristics, and robust short-circuit withstand capability into a single, industry-standard package.
