Per EIA/NARM standard RS–443, with VP = 200 V, which is the instantaneous peak of the maximum operating voltage.
Additional dv/dt information, including test methods, can be found in Motorola applications note AN1048/D, Figure 43.
All devices are guaranteed to trigger at an IF value less than or equal to the max IFT. Therefore, the recommended operating IF lies between
the device’s maximum IFT(on) limit and the Maximum Rating of 50 mA.
Current–limiting resistor required in series with LED.
Also known as “Zero Voltage Turn–On.”

Select the value of R1 according to the following formulas:
[1] R1 = (VCC – VF) / Max. IFT (on) per spec.
[2] R1 = (VCC – VF) / 0.050
Typical values for C1 and R2 are 0.01
µF
and 39
Ω,
respec-
tively. You may adjust these values for specific applications.
The maximum recommended value of C1 is 0.022
µF.
See
application note AN1048 for additional information on com-
ponent values.
The MOV may or may not be needed depending upon the
characteristics of the applied ac line voltage. For applica-
tions where line spikes may exceed the 600 V rating of the
MOC2A60, an MOV is required.

Use care to maintain the minimum spacings as shown.
Safety and regulatory requirements dictate a minimum
of 8.0 mm between the closest points between input
and output conducting paths, Pins 3 and 7. Also, 0.070
inches distance is required between the two output
Pins, 7 and 9.
Keep pad sizes on Pins 7 and 9 as large as possible
for optimal performance.
