Infineon IDWD20G120C5: A 1200V, 20A Dual IGBT Module for High-Power Switching Applications
The demand for robust and efficient power switching solutions continues to grow across industries such as industrial motor drives, renewable energy systems, and uninterruptible power supplies (UPS). Addressing this need, the Infineon IDWD20G120C5 stands out as a high-performance dual IGBT module engineered to deliver reliability and efficiency in demanding high-power applications.
This module integrates two independent Insulated Gate Bipolar Transistors (IGBTs), each rated for 1200V and 20A, within a single isolated package. This dual configuration is particularly advantageous for designing compact and efficient power stages, such as inverter legs in three-phase systems. The high voltage rating makes it suitable for operations directly from rectified three-phase mains voltages, while the substantial current capability supports significant power throughput.
A key feature of this module is its utilization of Infineon's advanced Trenchstop™ IGBT5 technology. This proprietary technology significantly reduces both saturation voltage (Vce(sat)) and switching losses, striking an optimal balance between conduction losses and turn-off behavior. The result is enhanced overall system efficiency, reduced thermal stress, and the potential for higher switching frequencies, which can lead to smaller passive components in the design.
The module also incorporates a co-packaged anti-parallel diode, essential for managing reverse recovery currents during switching cycles. This integration simplifies board layout and improves the reliability of the commutation loop. Furthermore, the module offers a wide operating junction temperature range of up to 150°C (Tvj op), ensuring stable performance in harsh environmental conditions and under heavy load cycles. The electrical isolation provided by the baseplate enhances safety and simplifies thermal management by allowing direct mounting to a heatsink.
Typical applications that benefit from the IDWD20G120C5's capabilities include:
AC motor drives and controls
Solar and wind power inverters
Industrial welding equipment
UPS and power supply units
