Triac power and thermal calculations
1. Introduction
Triacs are used to control AC mains loads. In the majority of applications, the triac will
dissipate sufficient power to make thermal considerations necessary. The size of
heatsink must be calculated and the maximum junction temperature must be predicted.
Such thermal design procedures must be followed if long-term reliability of the application
is to be assured.
Thermal design and analysis form an essential part of the design
and development process.
The thermal design requires several stages of calculation involving power, thermal
resistance and temperature rise. This Application Note introduces those calculations.
Worked examples are included, the data for which is derived from the customer’s
application or the triac’s data sheet.
2. Calculating triac power
Triac power dissipation is influenced by the load current. Full sine wave current (full wave
conduction) is assumed, since it presents the worst-case condition of maximum triac
power dissipation. It also makes for the easiest calculations. If calculations are required
for half wave conduction (e.g. for an SCR), please refer to the following subsection: “How
to calculate I
T(RMS)
and I
T(AVE)
for half wave conduction”.

– average load current (A). This value is calculated from the application’s RMS
load current using equation 2. (This assumes full wave conduction and sinusoidal load
current, which will give worst-case power dissipation.)
