6-Pin DIP Zero-Cross
Optoisolators Triac Driver Output
(800 Volts Peak)
The MOC3081, MOC3082 and MOC3083 devices consist of gallium arsenide
infrared emitting diodes optically coupled to monolithic silicon detectors
performing the function of Zero Voltage Crossing bilateral triac drivers.
They are designed for use with a triac in the interface of logic systems to
equipment powered from 240 Vac lines, such as solid–state relays, industrial
controls, motors, solenoids and consumer appliances, etc.

1. Test voltage must be applied within dv/dt rating.
2. All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between max
2.
IFT (15 mA for MOC3081, 10 mA for MOC3082, 5 mA for MOC3083) and absolute max IF (60 mA).
3. This is static dv/dt. See Figure 7 for test circuit. Commutating dv/dt is a function of the load–driving thyristor(s) only.

1. The mercury wetted relay provides a high speed repeated pulse
to the D.U.T.
2. 100x scope probes are used, to allow high speeds and voltages.
3. The worst–case condition for static dv/dt is established by
triggering the D.U.T. with a normal LED input current, then
removing the current. The variable RTEST allows the dv/dt to be
gradually increased until the D.U.T. continues to trigger in
response to the applied voltage pulse, even after the LED
current has been removed. The dv/dt is then decreased until the
D.U.T. stops triggering.
t
RC is measured at this point and
recorded.

Typical circuit for use when hot line switching is required.
In this circuit the “hot” side of the line is switched and the
load connected to the cold or neutral side. The load may be
connected to either the neutral or hot line.
Rin is calculated so that IF is equal to the rated IFT of the
part, 15 mA for the MOC3081, 10 mA for the MOC3082,
and 5 mA for the MOC3083. The 39 ohm resistor and 0.01
µ
F capacitor are for snubbing of the triac and may or may
not be necessary depending upon the particular triac and
load used.
