Result Interpretation

SiC MOSFET Steady-State Conduction Loss (Junction-Temperature-Dependent) calculator computes Conduction Loss Power in W using the defined engineering formula and the input values provided. Conduction Loss Power is expressed in W. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Drain RMS Current = 10
  • Reference On-Resistance at T_ref = 0.025
  • On-Resistance Temperature Coefficient = 0.0012
  • Junction Temperature = 300.15
  • Reference Temperature = 300.15

Expected Result:

  • Conduction Loss Power = 2.5

Engineering Interpretation:

Under the given input conditions, the calculated result is: Conduction Loss Power = 2.5 W.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
