The Infineon BSM50GB120DN2 is a 50A, 1200V dual IGBT module housed in the compact ECONOPACK DN2 package. Built on Infineon's proven NPT (Non-Punch-Through) IGBT technology, this module integrates fast-recovery freewheeling diodes and offers low V_CE(sat) characteristics that translate directly into reduced conduction losses and cooler operation under continuous load. The DN2 footprint provides straightforward PCB and heatsink integration, making it a practical choice for engineers designing space-constrained or replacement-critical power stages.

The BSM50GB120DN2 is well suited for a broad range of industrial power electronics applications including three-phase AC motor drives, regenerative drives, uninterruptible power supplies (UPS), solar inverters, induction heating systems, and servo amplifiers. Its 1200V blocking voltage provides adequate derating margin for 690VAC bus systems, while the 50A current rating covers a useful range of fractional to low mid-range motor drive power stages. The integrated freewheeling diodes eliminate the need for external discrete components, simplifying BOM and board layout.

Key Features of the BSM50GB120DN2:

• 1200V collector-emitter breakdown voltage (V_CES) with 50A continuous collector current rating
• NPT IGBT chip technology delivering low V_CE(sat) for reduced steady-state conduction losses
• Integrated co-pack freewheeling diodes with optimized reverse recovery characteristics for low switching losses
• ECONOPACK DN2 package with industry-standard footprint for simplified drop-in replacement and heatsink mounting
• Isolated copper baseplate for efficient thermal transfer to heatsink, rated for high power cycling endurance
• Short-circuit withstand capability supporting robust gate drive protection in fault conditions

Infineon's BSM50GB120DN2 carries a factory lead time of 99 weeks for new production orders — nearly two years from order to delivery. For maintenance teams managing unplanned equipment failures or procurement professionals trying to keep production lines running, that timeline is operationally unacceptable. OEM equipment using this module is still widely deployed in the field, and finding verified stock from a knowledgeable distributor is often the only viable path to a fast repair. ATI maintains inventory of hard-to-find, long-lead-time, and obsolete IGBT modules precisely for these situations.

ATI Accurate Technology is a power semiconductor distributor located in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts like the BSM50GB120DN2. Orders placed before 5PM EST ship same day. Volume pricing is available for MRO stockers and OEM procurement.
