We have an old batch of IR/Infineon IRF7739L1TRPBF from DC: 15+ - 16+.
These were bought from FD many years back before Infineon bought over IR.
Some records have not been properly kept.
We were looking for PCN to show that there were changes to the logo on the body marking of this chip IRF7739L1TRPBF.
Can someone please help validate that the logo (with a missing dash "-" on the logo) is a valid form with these lot numbers:
DC: 1646 Lot Code: 1019H8Q.1
DC:1646 Lot: 1019HQC.1
DC: 1524 Lot: 100Y1TM.1
Attached Pictures for reference and further investigations.
I guess it's going to be tough luck but I was hoping someone here is able to help.
Thank you in advance!Show Less
Hi, Please tell me about F3L400R07W3S5_B59.
If you check the internal circuit diagram, the IGBTs on the High side and Low side of the 3-level circuit are configured in parallel. What is the reason for this?
Hello, I am using an IGBT Module, for a three-phase inverter operation, and the input to the module is a DC Supply from a battery/bench supply. I would like to know any protection features that can be implemented, to prevent any damage by accidentally swapping the DC Supply terminals. Emphasis on avoiding the method involving a Schottky diode in the main DC Line, due to the usage of an IGBT Module and other constraints such as track width of PCB due to high currents being involved. Any alternate methods would be helpful. Thanks and Regards
This question was asked and answered back in Mar 2022:
The proposal replacement suggested by the distributor is wrong. The right replacement for IRGP4063D is IKW50N65ET7 https://www.infineon.com/dgdl/Infineon-IKW50N65ET7-DataSheet-v01_00-EN.pdf?fileId=5546d46272e49d2a01...
IKW50N65ET7 has short circuit capacity, also lower VCEsat, similar switching losses for the same Rg, and better Rg controllability than IRGP4063D. Therefore, perhaps you still need to adjust the Rg to match the current switching performance (dv/dt's and di/dt's) of your system using IRGP4063D."
I have the same problem of replacing the IRGP4063D part in an existing product (an offgrid 48V dc to 230VAC 5kW sine wave inverter)
The problem is that now in June 2022 the suggested part IKW50N65ET7 is on extremely long lead times and effectively unobtainable. Can Infineon suggest a part that is currently stocked (E14, Mouser, etc) that can be substituted?
There is a PLECS simulation file of FF1000R17IE4 on the home page.
There are 'FF1000R17IE4_diode.xml' and 'FF1000R17IE4_IGBT.xml' in the zip file.
Whether the model is about a single chip or equivalent block of parallel circuit?Show Less
I'm looking for the cad data FF1000R17IE4 for my study.
I need it for Ansys Q3D analysis to study about stray impedance of the IGBT module.
Where can I get the cad data??Show Less
Could you inform us the definition of Th about IKA15N65ET6 and any differences between Tc and Th ?
