MOSFET Power Dissipation Calculator

Calculate MOSFET Conduction Losses

Optimize your power electronics designs with our free online MOSFET Power Dissipation Calculator. Quickly determine conduction losses based on drain current (ID) and on-state resistance (RDS(on)) for efficient circuit analysis and component selection. This tool is essential for engineers and hobbyists looking to calculate power loss in MOSFETs and ensure reliable operation in various applications.

Formula:

Formula:

The MOSFET Conduction Loss (PD) is calculated using the following formula:

PD = ID2 ⋅ RDS(on)

Where:

  • PD = Power Dissipation / Conduction Loss (Watts)
  • ID = Drain Current (Amperes)
  • RDS(on) = On-State Drain-Source Resistance (Ohms)
