Frequently Asked Questions
What does this calculator calculate?
The MOSFET Steady-State Conduction Loss (Silicon) calculator estimates Conduction Power Loss based on the input parameters you provide
Why is drain-source on-resistance important in this calculation?
drain-source on-resistance is directly proportional to conduction power loss. When you enter drain-source on-resistance in ohm, the calculator uses it in the engineering formula to compute the output
How should I interpret the result conduction power loss?
The calculator outputs conduction power loss in W. For larger power values, divide by 1000 to express the result in kW, or by 745.7 for horsepower. The result is computed directly from the input values using the defined engineering formula
What units should I use for the inputs?
Enter each value in the units shown next to the input field: Drain-Source On-Resistance (ohm), Drain RMS Current (A). Make sure all inputs use the specified units for consistent results
What assumptions does this calculator use?
This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
