What is Power Dissipation of TRIAC ?

The power dissipation of a TRIAC is the total power that is lost or converted into heat when the device is in operation. This dissipation occurs due to the internal resistance and switching characteristics of the TRIAC. The conduction losses are the primary source of power dissipation in a TRIAC. To ensure the safe and reliable operation of a TRIAC, it's essential to make sure that the power dissipation does not exceed the device's specified limits. This can involve proper heat sinking and thermal management in high-power applications to dissipate the heat generated effectively.

How to Calculate Power Dissipation of TRIAC?

Power Dissipation of TRIAC calculator uses Maximum Power Dissipation = Knee Voltage*Average Load Current+Conductivity Resistance*RMS Current^2 to calculate the Maximum Power Dissipation, 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 is denoted by P_max symbol.
