Power Dissipation of TRIAC Solution

Follow our step by step solution on how to calculate Power Dissipation of TRIAC?

FIRST Step Consider the formula

P max(triac) = V knee(triac) \cdot I avg(triac) + R s(triac) \cdot {I rms(triac)}^{2}

Next Step Substitute values of Variables

∴

P max(triac) = 3.63V \cdot 0.081mA + 0.0103kΩ \cdot {0.09mA}^{2}

Next Step Convert Units

∴

P max(triac) = 3.63V \cdot 8.1E-5A + 10.3Ω \cdot {9E-5A}^{2}

Next Step Prepare to Evaluate

∴

P max(triac) = 3.63 \cdot 8.1E-5 + 10.3 \cdot {9E-5}^{2}

Next Step Evaluate

∴

P max(triac) = 0.00029421507W

Next Step Convert to Output's Unit

∴

P max(triac) = 0.29421507mW

LAST Step Rounding Answer

∴

P max(triac) = 0.2942mW

How to Evaluate Power Dissipation of TRIAC?

Power Dissipation of TRIAC evaluator uses Maximum Power Dissipation TRIAC = Knee Voltage TRIAC*Average Load Current TRIAC+Conductivity Resistance TRIAC*RMS Current TRIAC^2 to evaluate the Maximum Power Dissipation TRIAC, Power Dissipation of TRIAC is the amount of heat that is generated by the triac when it is conducting current. It is a function of the triac's on-state voltage drop, the load current, and the triac's thermal resistance. The on-state voltage drop of a triac is the voltage that is dropped across the triac when it is conducting current. The load current is the current that is flowing through the triac. The thermal resistance of a triac is a measure of how well the triac can dissipate heat. Maximum Power Dissipation TRIAC is denoted by P_max(triac) symbol.
