Core Product Features In-Depth
-
Advanced Trench Field-Stop (FS) IGBT Technology
- Technical Principle: This module utilizes Infineon's sophisticated Trench-Gate Field-Stop technology. Unlike older planar IGBTs, this structure dramatically reduces the collector-emitter saturation voltage (Vce(sat)). By optimizing the carrier concentration and electric field profile within the silicon, the device exhibits significantly lower power dissipation when it is in the "on" state.
- Application Value: A lower Vce(sat) directly translates to reduced conduction losses. For system designers, this means higher overall efficiency, lower operating temperatures, and a reduced need for bulky, expensive heatsinks. This allows for more compact and cost-effective system designs, a critical advantage in modern power electronics.
-
Integrated CAL (Controlled Axial Lifetime) Freewheeling Diode
- Technical Principle: The BSM300GA120DN2 incorporates a precisely engineered freewheeling diode (FWD) with "soft" recovery characteristics. This means the diode turns off smoothly with a controlled di/dt and low peak reverse recovery current. This behavior minimizes high-frequency voltage oscillations and overshoots during switching events, a common source of EMI and device stress.
- Application Value: The soft-recovery diode drastically simplifies the design of the surrounding circuitry. It reduces or eliminates the need for external snubber circuits, saving board space and component costs. Furthermore, by generating less electromagnetic interference (EMI), it simplifies EMC compliance, shortening the product development cycle and improving system reliability by preventing destructive voltage spikes.
Typical Applications and Value Proposition
- Industrial Motor Drives: In high-power AC drives and servo controls, the BSM300GA120DN2's low conduction losses minimize heat generation within the inverter cabinet. Its robust CAL diode safely handles the high inductive currents from motor windings during dynamic load changes, preventing failures and enhancing the drive's durability.
- Uninterruptible Power Supplies (UPS): Efficiency is paramount in online UPS systems to reduce energy costs and maximize battery runtime. This module's high efficiency directly contributes to a lower Total Cost of Ownership (TCO). Its proven reliability ensures the UPS performs flawlessly during critical power outages.
- Welding Equipment: Modern welding systems require precise, high-frequency control of the welding arc. The fast yet soft switching performance of the BSM300GA120DN2 enables stable arc control for superior weld quality while its thermal ruggedness withstands the demanding, high-current pulse cycles typical of welding applications.
- Solar and Wind Power Inverters: In renewable energy systems, every watt of power saved matters. By minimizing conversion losses, this IGBT module helps maximize the energy yield from solar panels or wind turbines, improving the overall return on investment for the installation.

Product Comparison and Selection Advice
When designing a three-phase inverter, engineers often weigh the benefits of using three discrete half-bridge modules like the BSM300GA120DN2 against a single, integrated Power Integrated Module (PIM) or CIB module. The BSM300GA120DN2 offers superior design flexibility, allowing for optimized PCB layouts and distributed heat dissipation, which is crucial for maximizing power output and reliability in systems above 50kW. While a PIM simplifies assembly for lower-power systems, the modular approach with the BSM300GA120DN2 provides better thermal management and serviceability in high-power industrial automation.
