I simulated the IMW120R020M1H and IMW120R045M1 pspice models using the spectre simulator of candence company, but encountered the following problems:
warning （ASL-6252）: " Internal (bsource )" 0 : I6.X$M009F.X$M01LF.G01NW : a domain error occured while calculating cosh(x) because a large value 540.624743 has been specified for x . The value has been clamped to 500.
warning （ASL-6254）: " Internal (bsource )" 0 : I6.X$M009F.X$M01LF.G01NW : a domain error occured while calculating sinh(x) because a large value 540.624743 has been specified for x . The value has been clamped to 500.
And many questions like the above.
The I6 is IMW120R020M1H or IMW120R045M1 .
I don't know where the problem is !

How to solve this problem？

Hello. I want to find Coss vs. Vds curve in MOSFETs using the .txt file containing the MOSFET's SPICE code. Can you please tell me how I can do it?

P.s.: I don't want to use hspice or ltspice or plecs. Is it possible to find the curve just by the .txt code file?

Hello,

I have some problem on the parts IPD350N06LGBTMA1.
Why are they look like oxidzation. Is it normal and no any affect to be using? Please find the attached photo.

Thanks

Hello Infineon team,

I am trying to simulate the IMW120R007M1H_L3 in LTspice (half bridge configuration). There seems to be an issue with the model, certain nodes are floating. My simulation terminates immediately after starting and I am not able to get the results.

How can I solve this issue?

I have attached the model and the error message.

Best, Milos

P.S. Do you have an L1 model of the MOSFET in question that you can provide? I don't really require temperature dependent model.

Hello

Does Infineon have complementary MOSFETs (Nch_Pch ) for Audio  _traditional Hi-Fi_Class-B amp?

VBRDSS> 150V , Id> 33A  @25deg-C  is   required.

I found ipb720p15lm for Pch,  but I could not find  similar Vth, VGS-Id characteristics for Nch MOSFETs.

I think IPB200N15N3 may be candidate, but  Vth is different.

Please advise.

Thank you for your help.

Hi community friends,

I’ve got a standard package of part#IAUT150N10S5N035 from the distributor. We’ve done the IQC inspection and went to test & verify in White Horse labs.

When test the X-Ray and Decapsulation, the interior shows different compare with another same models. Some friends told this was not produced in Infineon Melaka, but suspect it was produced by Sub-con. Below I will enclose pictures for further check, if someone else help to check its real factory that will be much appreciated.

1. Label information

2. External Visual Inspection

3. X-Ray inspection

4. Internal Die Verification

We find its internal structure is different with another same part produced Malaysia, please help to check this part's real factory.

Thank you.

Dear Team,

I am simulating the double pulse test in LTspice to observe the switching behaviour. But I have query about parasitic components of MOSFET inside spice model of SiC Mosfet like package inductance, Parasitic capacitance and body diode. Those components are already considered in the spice model or I need to add separately in the simulation circuit? 

Thanks and Regards,

Hi all,

I wonder if there are L1 Spice models of the captioned device or if anyone has tested the existing libraries (that contain L3 models) in LTSpice?

Thanks

Hi,

I will be using the IRHQ567110SCV for a space grade design. I want to buy a cheaper alternative for my commercial breadboards and was wondering if you could recommend a device.

I got a quote for the IRHQ567110 and it had a lead time of 17 weeks.  I see on the datasheet there is a IRHQ567110SCS but don't know if its truly a commercial part.

Thanks!
