Frequently Asked Questions

How do I coordinate fuse I2t with IGBT withstand?

Ensure fuse clearing I2t < 0.8 x IGBT withstand I2t. Check datasheets for values at same fault current and time. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

Compare fuse and IGBT I2t with 20% safety margin.
