Show LessHello experts.
As we know, the HybridPACK IGBT module can be assembled by press fit process. Here is a problem I want to discuss with you about the Z-direction tolerance: In the 2D drawing of IGBT module, the tolerance of press fit pin height is +0.4/- 0.5mm. The PCB thickness is 1.6 +/- 0.16mm. If the PCB thickness reaches the lower limit, 1.44mm, the center of press fit area will not be aligned to the PCB center. Is it possible that the pin press fit area get close to the PCB surface or get out of the PCB hole partially? What is the influence of pin shift in the PCB hole? Will it affect the push out force and reliablitiy test (such as vibration)?
Thanks

Show LessHow should I choose the horizontal and vertical tube current parameters in a T-type NPC topology? Also in a typical combination scheme of FF2400RB12IP7 + FF1800R17IP5 x 2, what is the maximum current that can pass through this application combination? Thanks!

Show LessHello, Infineon
I'm currently working on IGBT IKW75N65ET7. If a 50HZ sinusoidal current with an amplitude of 108V is applied to the gate. Will it damage the chip. Looking forward to your reply.
Sincerely.
Sick.

Show LessUnder the ANPC topology, calculations were performed with the FF900R12ME4 product module data, changing the drive resistors to 0.51 and 5 ohms, respectively, and there was no difference in the loss and junction temperature calculations, which were the same.

Show LessHello! Can you tell me what are the main characteristic parameter differences between the igbt high speed switching series, and the low speed switching series? Why are there these differences, and which part of the device structure is responsible for them?
In addition, some application manuals often refer to the " Softness and snap-off behavior " of IGBTs, can you help provide detailed information to help us understand this behavior of IGBTs more clearly?
thanks

Show LessHello,
We conducted static and dynamic tests on IKY140N120CH7 and IKQ140N120CH7 single tubes respectively before the products were introduced into UPS, and found that VCESAT with Kelvin was lower, and the turn-off spike and gate waveforms were different, and we would like to inquire about the reasons for this.
