Dear Infineon team,
I have an issue with using Infineon Spice model in LTspice as shown in attached picture. I think it is about the setting up of Tj and T1 terminals for junction temperature and case temperature.
The device I use is IPWS65R022CFD7A.
Could you please help me to solve this issue?
Many thanks.

What is the ‘Maximum Pulsed Source to Drain Diode Forward Current’ for the part IPA65R150CFDXKSA1?
I think there is a loss due to Coss(esr) when zvs.
Is there a way to find the loss?
Hello,
We are using the Power MOSFET IPB083N15N5LF in our power supply product.
I have a question on the safe operating temperature range measured on the package top face.
In our product the bottom tab is mounted on the heatsink.
When I measure the temperature at the package top face by using a thermocouple under the rated load, it is measured as 73℃ for the environmental temperature of 27℃.
Therefore we suppose that the temperature at the package top face under the rated load would be 96℃ and 117℃ for the environmental temperature of 50℃ and 71℃ respectively.
I wonder how much the Power MOSFET IPB083N15N5LF is safe when the temperature at the package top face is measured as 96℃ and 117℃ respectively.
Thank you for your guidance.
With regards,
GKIM

How to quantify the tpulse,positive<=1%dutycycle/fsw test condition for Vgs transient?
we compare other trench gate vendor, just show simple test condition such as tsurge < 300ns.

Can you help to provide equivalent for IRLL3303PBF
Thanks

How should an SOA be altered for low temperature? At high temperature (above 25C), the SOA must be derated. Does the SOA increase at temperatures below 25C? Specifically looking at PN: irhna597260

According the title of matter, we received this question from Japanese customer will purchase SiC modules.
If there is permissible and conclete values and times for gate overshoot/undershoot, could you tell me the information?
The detail of this question is following and described in attached PDF file.
0.Original gate bias is seemed as +15V/-9V. Furthermore, this SiC has already worked in buck converter at test.
Test condition: Vin=830V, Vout=400V, Pout=50kW, duration term=5 hours.
1.It's monitored undershoot of minus gate voltage, but this voltage difference is very small. (Rated: -10V <=> Monitored: -10.4V)
2.This voltage undershoot is very short term from waveform. It seems under 100ns, probably under 20 ns or less.
I think this undershoot won't affect the SiC MOSFET, but I can't tell to customer without confirmation.
If there is any questions, please let me know it.
