t(delay), t(f) versus IFT
The POWER OPTO Isolators turn on switching speed con-
sists of a turn on delay time t(d) and a fall time t(f). Figure 13
shows that the delay time depends on the LED trigger cur-
rent, while the actual trigger transition time t(f) stays constant
with about one micro second.
The delay time is important in very short pulsed operation
because it demands a higher trigger current at very short trig-
ger pulses. This dependency is shown in the graph IFT ver-
sus LED PW.
The turn on transition time t(f) combined with the power
triacs turn on time is important to the power dissipation of this
device.

MOC2R60
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
μ
F and 39
,
respectively. You may adjust these values for specific
applications. The maximum recommended value of C1 is
0.022
μ
F. See application note AN1048 for additional
information on component values.
The MOV may or may not be needed depending upon the
characteristics of the applied AC line voltage. For
applications where line spikes may exceed the 600 volts
rating of the MOC2R60, an MOV is required.
