IGBT Module Voltage Class

IGBT (Insulated Gate Bipolar Transistor) modules are categorized into distinct voltage classes based on their collector-emitter breakdown voltage (V_CES), ranging from low-voltage industrial drives to high-voltage power transmission systems.

Common IGBT Module Voltage Classes

600V / 650V Class: Used in low-voltage motor drives, home appliances, solar micro-inverters, and power supplies.

1200V Class: Standard for industrial motor drives, un-interruptible power supplies (UPS), and electric vehicle (EV) inverters operating on typical 400V–600V DC links.

1700V Class: Applied in heavy-duty industrial drives and 690V AC grid applications.

2000V / 2500V Class: Specialized mid-range classes designed for 1500V DC renewable energy systems (like large photovoltaic and wind converters).

3300V Class: Utilized in traction drives (light rail, locomotives), medium-voltage industrial drives, and renewable energy distribution.

4500V Class: Advanced trench/field-stop modules bridging the performance gap between 3.3 kV and 6.5 kV for high-power transmission and distribution.

6500V Class: Deployed in heavy-duty high-voltage direct current (HVDC) systems, railway traction, and grid infrastructure.
