The BSM75GB120DN2(SCH100)-EUPEC is a 75A, 1200V dual IGBT module manufactured by Eupec (now Infineon Technologies) using the SCH100 IGBT chip platform. Housed in the industry-standard DN2 package with an isolated copper baseplate, this module integrates two IGBT switches with co-packed anti-parallel freewheeling diodes, enabling half-bridge or phase-leg topologies. The SCH100 chip generation is engineered for low conduction and switching losses, delivering high efficiency across a wide operating range while maintaining robust short-circuit withstand capability critical to industrial power conversion designs.

This module is widely deployed in variable frequency drives (VFDs), servo amplifiers, regenerative AC drive systems, UPS inverters, and medium-power induction heating equipment. Its 1200V blocking voltage and 75A continuous current rating make it well-suited for 480–690VAC line-fed systems where adequate voltage derating is required. OEMs and MRO teams will find this part in legacy Siemens, ABB, Danfoss, and Yaskawa drive platforms, as well as in custom-built industrial inverter designs where the DN2 footprint and gate drive characteristics are already engineered into the PCB layout.

Key Features of the BSM75GB120DN2(SCH100)-EUPEC:

• 1200V collector-emitter voltage (VCES) with 75A rated collector current — suitable for 480–690VAC bus applications with standard derating margins
• SCH100 IGBT chip technology delivering optimized trade-off between switching losses (Eon/Eoff) and conduction losses (VCEsat) for high-frequency inverter operation
• Integrated anti-parallel CAL (Controlled Axial Lifetime) freewheeling diodes for soft recovery behavior and reduced EMI in hard-switching topologies
• Isolated AlSiC or copper baseplate in the DN2 package for direct mounting to heatsink, with industry-standard power terminal and gate/auxiliary terminal layout
• Designed for short-circuit withstand capability (tSC ≥ 10µs) providing critical protection margin in drive and inverter fault conditions
• Compatible with standard Eupec/Infineon DN2 footprint, enabling direct drop-in replacement in existing PCB and busbar designs

The BSM75GB120DN2(SCH100)-EUPEC is a legacy Eupec part that transitioned under the Infineon brand consolidation, making it increasingly difficult to source through standard distribution channels. Lead times from authorized distributors can stretch 16–26 weeks or longer when production runs are limited, creating critical downtime risk for facilities dependent on this specific module. ATI Accurate Technology maintains inventory of hard-to-find, long-lead-time, and obsolete power semiconductors precisely for these situations — so your line doesn't wait on a supply chain backlog.
