Power Loss in MOSFET Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Power Loss = Drain Current^2*Drain Source Resistance
Ploss = Id^2*Rds
This formula uses 3 Variables
Variables Used
Average Power Loss - (Measured in Watt) - Average power loss is the power loss when transistor device is in working state.
Drain Current - (Measured in Ampere) - Drain Current is the current that flow through the drain junction of the MOSFET and IGBT.
Drain Source Resistance - (Measured in Ohm) - Drain source resistance in MOSFET is defined as the opposition faced by the current flowing through the drain source terminals.
STEP 1: Convert Input(s) to Base Unit
Drain Current: 105 Milliampere --> 0.105 Ampere (Check conversion ​here)
Drain Source Resistance: 17 Kilohm --> 17000 Ohm (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Ploss = Id^2*Rds --> 0.105^2*17000
Evaluating ... ...
Ploss = 187.425

What losses occur in a MOSFET?

MOSFET working and construction follows the same pattern as for BJT, therefore the type of losses are same in both BJT and MOSFET. MOSFET faces losses due to switching operations and other are conduction losses.

How to Calculate Power Loss in MOSFET?

Power Loss in MOSFET calculator uses Average Power Loss = Drain Current^2*Drain Source Resistance to calculate the Average Power Loss, The Power Loss in MOSFET formula is defined as the power dissipated when a MOSFET starts conducting. Average Power Loss is denoted by Ploss symbol.

How to calculate Power Loss in MOSFET using this online calculator? To use this online calculator for Power Loss in MOSFET, enter Drain Current (Id) & Drain Source Resistance (Rds) and hit the calculate button. Here is how the Power Loss in MOSFET calculation can be explained with given input values -> 187.425 = 0.105^2*17000.
