Switching time of a TRIAC
It's not listed in the datasheet. It's typically in the 100ns range once it triggers (2us typical) and regenerative action occurs, so it is negligible in a typical mains-switching application. Typically turn-off occurs at the current zero crossing.
You must make sure that the rate-of-rise of current does not exceed the datasheet &quot;limiting value&quot; \$dI_T/dt\$ during the switching or the triac may be damaged. This is a function of the circuit you have it connected in.
Many triacs list a critical rate of change of commutating current for turn-off characteristics, but I don't see that here.
