Hello, we bought a Siemens thermal resistance tester and found that the testing of Infineon modules is quite different from the specification? Can you tell me if the Infineon thermal resistance test is also done with the Siemens machine? Is it water cooled?

Show LessHello, We have FS100R12W2T7 module in use, but the module Datasheet doesn't have SC data labeled TC=25C, can I simply calculate the short circuit current for TC=25C based on the trend of 175C-150C?

Show LessHi Experts, Recently I was evaluating the dynamic performance of GaN MOS, the device model is GS-065-030. while doing the double pulse test, I found that the Ids current oscillates badly during switching, which makes it impossible to estimate the switching loss and other parameters. May I ask what could be the cause of this?
The measured waveforms are shown below, the blue Vm channel is the Ids current waveform grabbed using the SSDN-414-010 (10mohm) shunt. The purple color is the waveform grabbed using the current probe at the load inductor side.

Show LessHi all,
I think that the data format of vout_transition_rate and ton_rise is Linear.
The values of vout_transition_rate and ton_rise are as follows.
In decimal format, vout_transition_rate is 1(8×2-3)[V/ms].
In decimal format, ton_rise is 1(2×2-1)[ms].
Are these correct?
Also, please teach me what u7.3 and s-1.7 stand for.
Best regards,
MS
I hope this message finds you well. I am reaching out regarding a couple of questions I have about the datasheet for the IR2109(4)(S).
Firstly, I am curious about the capacitor specifications mentioned in the datasheet. I noticed that polarized capacitors are recommended for certain applications. However, I am interested in exploring the possibility of using non-polarized capacitors instead. Could you kindly provide some insight into whether non-polarized capacitors can be safely substituted for the polarized ones mentioned in the datasheet?
Secondly, upon attempting to calculate the value of the bootstrap capacitor using the provided formula, I encountered an unexpected result. Specifically, when I substituted the given values into the formula, I found that the denominator resulted in a negative value: (Vcc - Vf - VLs - Vmin) = (12V - 1V - 2.35V - 9V) = -0.35V. This negative value raises some concerns and prompts me to seek guidance on how to proceed with determining the appropriate value for the bootstrap capacitor. Could you please provide clarification on whether a negative value in this context is valid, or if there might be an alternative method or consideration to account for in this calculation?
I understand the importance of adhering to recommended component specifications and calculations, but I am curious about any potential flexibility or alternative approaches in these matters. Any guidance or clarification you could offer on these issues would be greatly appreciated.
Thank you very much for your attention to these inquiries. I look forward to hearing from you soon.
Best regards,
Show LessI would like to know if the solid state relay RDHA710SE10A2FK can conduct bipolar currents for an AC application.
Any suggestion for a SPICE model is also very welcome.
Show LessCould you please teach the failure rate of the VCP function (17pin) of TLE9461ES?
The gate signal of the battery's reverse connection protection FET is driven by this charge pump. If the VCP function is lost, the system may malfunction. Therefore, I would like to know the failure rate of individual parts.
Best Regards,
Tetsuo
