C3M0160120J Ltspice model

matbob

Hello,

I am doing an Ltspice simulation using the C3M0160120J Spice model. I found that the values of some of the parameters provided the in datasheet do not match with the Spice model. For example:

1. Thermal Resistance from Junction to Case (Rjc ) provided in the datasheet is 1.38 C/W but in the model, this is about 1 C/W.
2. Internal gate resistance (RG(int)) provided in the datasheet is 8 ohms, but in the model it is 2.6 ohms.

Which values are correct?

Thanks!

Hello,

Thank you bringing this discrepancy to our attention. We apologize for the issue you are experiencing. The model is likely an older version, which may not reflect the latest datasheet parameters.

Here is the updated version of the C3M0160120J Spice model.

Hello,

Thank you for providing the updated model.

I tired using the new model in my simulation, however, the simulation fails with "Time step too small" message. Reverting to the older model or some other device model works.

Can you please check the device model once again. I am attaching a sample Ltspice simulation here. It is a simple half-bridge switching at 50 percent duty cycle.
