Where can we obtain the latest version of data sheets?
The data sheets can be downloaded from Fuji Electric web site. The use of parametric search is recommended. Please contact Fuji Electric Corp. of America or your local sales representative or distributor to answer your question.

Why do the currents balance if IGBTs with positive temperature coefficients are connected in parallel?
“Let’s consider the case where two IGBTs with different VCEsat are connected in parallel.
(1) A larger amount of the current will flow through the IGBT with smaller VCEsat.
(2) Due to the larger current flow, the total loss of the IGBT becomes large and the junction temperature increase.
(3) If the IGBT has a positive temperature coefficient, VCEsat increases with increasing junction temperature Tvj and hence, the current will decrease until current balance is achieved.” -
What are the selling points of 7th Generation X Series IGBT Modules?
“(1) Low power dissipation
Compared with Fuji’s conventional products (the 6th Generation V Series), power loss during inverter operation is reduced by 10%.
(2) Miniaturization
By suppressing heat generation together with power loss reduction, miniaturization of about 36% is achieved compared with conventional products.
(3) High temperature operation and high reliability
Implementation of continuous operation at the maximum junction temperature Tvjop of 175oC, and improvement of reliability.
For details, please refer to 7th Generation IGBT Module "X Series" New Product Information.” -
What is “short-circuit withstand capability”?
In the case of excess current due to an accident or abnormal operation of an inverter device, the time from the start of the short-circuit current until the IGBT breakdown is called the short-circuit withstand capability. The protection circuit has to be designed to detect excess current in a short time not exceeding the short-circuit time and to turn off the gate pulse.
-
Can I get short-circuit withstand capability data?
The short-circuit withstand capability varies with chip generation and withstand voltage. Technical documents that show the relation of the short-circuit withstand capability tSC as a function of DC voltage VCC are available. Please download them from our web site.
