Key Selection Criteria
Power Requirements
Consider voltage and current requirements, including worst-case operating conditions and safety margins. Account for derating in harsh thermal environments.
Switching Frequency
Higher frequencies require devices with lower switching losses. Consider the trade-off between switching and conduction losses for your operating frequency.
Thermal Management
Assess available thermal management and cooling options. Higher power density applications may require advanced thermal packages.
System Integration
Determine if module (IGBT, IPM, PIM) or discrete approach better fits your application. Consider board space, assembly complexity, and system reliability.

Access ToolExpert Selection Advice
Our field application engineers have extensive experience helping customers select the right Fuji Electric components for their applications. When in doubt, consider the following factors:
- Start with voltage rating: choose at least 1.5x operating voltage
- Consider current rating with appropriate derating for thermal conditions
- For high-frequency applications, prioritize low switching losses
- For high-efficiency applications, optimize for total losses (switching + conduction)
- Consider system-level integration requirements (protection, control, etc.)
