MOSFET (Si/SiC) Forum Discussions

The mosfet I am using for my project is https://www.infineon.com/cms/en/product/power/mosfet/automotive-mosfet/iaua250n04s6n005/#!support

I am not sure how to calculate power loss. 

In my project I am not using fixed frequency for mosfet On/Off, It means I have to turn on/off mosfet according to the voltage / variable value that is change all the time so the mosfet will turn on/off random manner.

for instance,  1 0 1 1 1 1 0 1 0 1 0 0 0 0 0 0 0 1 0 1 0 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1 1 0 0 1 0 1 0 1

where; 1 for mosfet ON and 0 for mosfet OFF

Our customer got  the parts PN:IPW65R080CFDA but  the parts in the tubes are with different markings (See attached pic)

The fab code is different .So is it normal?

Hi all,

I want to simulate the Tj of a MOSFET by reading the actual measured VDS and IDS switching waveforms using LTSpice.
The Infineon IGBTs have a description of the RC thermal model in the datasheet and can be simulated using this value, but CoolMOS and Optimos do not have this information and cannot be simulated thermally.

However, I look at the lib files provided on the web, I see the RC thermal model.
For example, IPB027N10N3 would correspond to the part in the red box below.

If I could extract this parameter, it would be possible to perform thermal simulation with VDS,IDS with real waveforms as well as IGBTs, but is it possible to extract only this parameter?

If there is a better way, I would appreciate it if you could let me know.

Regards,

For a new BMS project, I would like to ask regarding the 2ED4820-EM:

1. Can it be used with back-to-back source configuration for bidirectional current control? The current flow will have 2 directions, one for load connection and one when the charger is connected
2. Can we use one channel as a low-side MOSFET driver? On your site is says that it is possible at the expense of increased current on VBAT (+8mA) but there no any reference design

Thank you

I want to use MOSFETs as a controlled pluse load. How do I choose a suitable MOS that has a wide SOA(tolerate a single pluse of 20V/10A/10msTon/1Hz)

Hello All,

Is there possibility to get thermal characterization parameter : psi JT for IPD25CN10N G in TO252-3 package?

I'm trying to figure out Tj based on thermocouple measurement on top of the package case...

Thanks!

Hi,

In order to compare the power dissipation of different discrete power semiconductors (SiC FETs and IGBTs), I would like to compare them both in a 2-level and in an NPC1 topology.
The problem: some show up in the corresponding topologies, others don't, which is probably related to the given parameters.
My questions on this:
1. is there a list of components available in IPOSIM?
2. is there somehow a possibility that I can use any components available in IPOSIM also in different topologies?
I already tried to activate the "single switches" in the NPC topology, however the desired components did not show up there.
Examples:
- IKW75N65, IKW50N120 and IKZA75N65
- IMZA65R030 and IMBG65R030

Thanks in advance!

Part "IRFS38N20D" got Discontinued, whether "IRFS38N20DTRLP" or "IRFS38N20DTRLPbF" is replacement part?

Also please confirm, all Electrical specs and Mechanical dimensions are still the same?

dear ,

Based on PLECS model, what simulation software should I use? Whether you need to build a model?

Could you help give me a suggestion？
