* This optoisolator should not be used to drive a load directly. It is in-
tended to be a trigger device only.
Additional information on the use of optically coupled triac
drivers is available in Application Note AN–780A.
In this circuit the “hot” side of the line is switched and the
load connected to the cold or ground side.
The 39 ohm resistor and 0.01 µF capacitor are for snub-
bing of the triac, and the 470 ohm resistor and 0.05 µF ca-
pacitor are for snubbing the coupler. These components
may or may not be necessary depending upon the particu-
lar triac and load used.
