Simulation model for C3M0900170J

Hello,

I have a question regarding the simulation model of the "C3M0900170J" MOSFET.

For my design, I would like to simulate the circuit with the C3M0900170J in SIMPLIS.
The reason is that other components of the circuit are only available in SIMPLIS.

Thus, I would like to know if the simulation model of the C3M0900170J can be made available for SIMPLIS.

Thanks in advance!

Best regards,

Thomas

    Hello,

    Thank you very much for your help!

    I tried to install the model and use it in SIMPLIS.

    Unfortunately, it only works for me in SIMetrix and not in SIMPLIS.
    Is there anything special I have to do? Does it work in SIMPLIS for you?

    Thanks,
    Thomas

    Hello,

    Attached is the SIMPLIS-compatible SPICE model. To use this model in SIMPLIS, please follow these steps:

    1. Add the Library: Go to File -> Model Library -> Add/Remove Libraries… and add the .lib file. Alternatively, you can drag the model directly into the Elements command shell.
    2. Place the Device: Navigate to Place -> From Model Library… (or use shortcut CTRL+G). A pop-up box labeled “Select Device” will appear. Select C3M0900170J_Simplis and click the "Place" button.

    3. Extract Parameters: After placing the device, a new pop-up titled “Extract MOSFET Parameters” will show up. Here, you need to select the relevant parameters to linearize the SPICE model and extract its equivalent linear SIMPLIS model.

    If you have any further questions or need additional assistance with the SIMPLIS model, please feel free to ask!

    Hello,

    Thanks a lot for that SIMPLIS model!

    I have tested the model and it works fine in principle.

    However, I have a question related to the model behavior.
    I've created a small test-simulation model (see picture below).
    The behavior in the On-state is as expected according to the datasheet.
    However, in the Off-state, there is a voltage-drop across the pull-up-resistance R1 (1kOhm) of around 107V. This means that there is a leakage current of around 100mA flowing through the mosfet.
    This is far more than what I would expect according to the datasheet.

    Do you agree that the off-state behavior of the model is different to what you would expect?
    If so, could you refine the off-state behavior of the model?

    Thanks,
    Thomas
