Hi all,
The IKB20N60T datasheet specifies an absolute maximum rating of Ic=28A (Tc=100°C), but the beginning of the datasheet says Ic=20A.
5357.attach
5358.attach

When I checked the other part numbers, both IKD15N60R matched with Ic=15A, but IKB15N60T was the same as IKB20N60T and the collector current description did not match.
What does Ic=20A in IKB20N60T indicate?
Also, why do some part numbers have the same Ic value and others do not?

Thank you

Hi Yuki,
the value indicated at the beginning of the Infineon IGBT datasheet, and contained in the Infineon part number name, is usually referred as nominal device current. That is the current that is conventionally used to indicate static parameters (like VCEsat and VF), and dynamic parameters (like energy losses and switching times). It is also used to define the maximum pulse current capability of the IGBT.

The nominal current values is not necessarily equal to the maximum DC collector current, that, in case of the IKB20N60T, is equal to 28A, as you pointed out correctly. However, this relation between nominal current and DC collector current is usually valid for all the devices: IC,nom≤IC.

Hope that this answer your question.

Best Regards,
Giuseppe
