Hi. For the BSC032NE2LS, the part and footprint drawings are different between the datasheet vs the Packaging -> Package Data link off the product page. Which one is correct for this part?

Thanks
Show LessHello. We bought an EXCLUSIVE information design EVAL_3KW_50V_PSU from you. We believe that the firmware is not suitable for this device. This firmware follows the design reference EVAL_3K3W_LLC_HB_CFD7.
The project was downloaded on 11/18/2022 as part of a file
"Infineon-P100002802_EVAL_3KW_50V_PSU-AdditionalProductInformation-v01_00-EN.zip"
1. File size 50V_PFC_productive.hex 0 bytes?
2. The project is damaged, below are the signs of damage.
When exporting a project from the file "SiC_3000W_CCM_PFC_OCP.zip" a message appears
3. HW Signal Connectivity does not contain any connections:
4. On the "Problems" tab there is a list like this

Hi,
I am looking for 200V N-Channel SOT-23 package MOSFETs with Rodson of less than 30Ohm. Please let me know if near matching spec. parts available.
Best Regards,

Show Lesspart number is IAUT150N10S5N035, assembled in Malaysia, packed in MBB with desiccant and HIC, is this common for you?
We have been successfully using these two MOSFETs for three years on our low volume custom boards. We have roughly 65 boards in existence with 9 instances of BSC100N06LS3GATMA1 and 3 instances of BSC067N06LS3GATMA1 on each board. This circuit has never had a single problem until our last run of 14 boards. These 14 boards had very minor part changes from the previous iteration, but none of which would have had any affect on this circuit as these are all in an isolated design. They do run flying probe testing after PCBA, and they reported that it passed that test.
On these 14 boards, we had 3 boards with a failure with at least one of these parts which we could narrow down to four MOSFETs. Based on electrical waveform analysis it appeared to be an issue in the power stage of the design so I requested X-Rays on these MOSFETs and the controller IC. After reviewing the X-Rays it looked to me like there was possibly excess solder voiding which was maybe limiting current transmission. The application is a 5A/48VDC output buck DC/DC which is only dropping the input voltage by roughly 5V. 250W of output is required. I am not an expert in solder void analysis and would like additional opinions from the community on that. Those X-Rays are attached here- note that the vias under the pad are filled with resin.
I asked the assembler to remove those parts, clean them, and replace them to see if it fixed the issue, and it did in fact correct the issue on the first board. We have two more that I also suspect it will correct it, but I have asked him to hold off on reworking until we can come up with an isolation procedure to verify the root cause.
I asked the assembler to supply more information about the source of the parts and the storage. The BSC067N06LS3GATMA1 parts were received from a broker due to supply shortages, and they were not received or stored in moisture sealed packaging. Upon observation under a microscope they believe they saw oxidation on the leads of one of the unused parts. That picture is included as an attachment. The BSC100N06LS3GATMA1 were received from Mouser and were stored appropriately.
Which is more likely to be the issue? The first experiment of removing the issue and manually replacing would have also cleaned the oxidation off of the parts. I also don't generally feel like for just the small current we are talking about on these that the solder voiding is extreme enough to cause the issue. This is not a finger pointing exercise- it is simply trying to understand and prevent issues on upcoming builds.
Thanks in advance!
Show LessHow can I find out the export control category for part number JANTXVR2N7550T1? It is not found in Infineon's ECCN and HTS finder
I am designing a bldc controller. For that as a power switching I chose the ipb042n10n3-g. Can you suggest any 3 phase gate driver that will match this MOSFET?
Switching frequency is 20khz

I downloaded Models of MOSFET CoolSiC 650V from the Infineon official website(https://www.infineon.com/cms/en/product/power/mosfet/silicon-carbide/discretes/imw65r030m1h/?tab=~%27simulation_models#!designsupport ), and tried to simulate in Pspice, but an error was reported. The device I am using is IMW65R030M1H_L0. The specific error content is:

I searched for relevant information for a long time but failed to solve it. There was even a post that was very similar to my problem, but I couldn't get a feasible solution(https://community.infineon.com/t5/MOSFET-Si-SiC/Ask-for-the-PSpice-model-of-650V-SiC-Trench-MOSFETs/m-p/312765#M1349 ).
I hope to get help from everyone in the community, thank you very much!😊😊😊
Hi, Infineon
I want to know that is there a program in this kit?
Do I need to reprogram or Just modify the parameters directly when I use it.
Show Less1. Calculation of Eon/Eoff after Power loss adjusts Rg & Calculation of film cap capacity of IN CAP
2. Does the Module lead resistance parameter in FS03MR12A6MA1LB have values corresponding to 125 degrees and 150 degrees? Or is there a calculation method?
3. Design documentation for Dead time.
