GlobalOptoisolator™
6-Pin DIP Zero-Cross
Optoisolators Triac Driver Output
(400 Volts Peak)
The MOC3041, MOC3042 and MOC3043 devices consist of gallium arsenide
infrared emitting diodes optically coupled to a monolithic silicon detector
performing the function of a Zero Voltage Crossing bilateral triac driver.
They are designed for use with a triac in the interface of logic systems to
equipment powered from 115 Vac lines, such as solid–state relays, industrial
controls, motors, solenoids and consumer appliances, etc.

Test voltage must be applied within dv/dt rating.
All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating IF lies between IFT
(15 mA for MOC3041, 10 mA for MOC3042, 5 mA for MOC3043) and absolute max IF (60 mA).
This is static dv/dt. See Figure 7 for test circuit. Commutating dv/dt is a function of the load–driving thyristor(s) only.

D.U.T.
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.

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, 5 mA for the MOC3043, 10 mA for the MOC3042, or
15 mA for the MOC3041. The 39 ohm resistor and 0.01
µF
capacitor are for snubbing of the triac and may or may not
be necessary depending upon the particular triac and load
used.
* For highly inductive loads (power factor < 0.5), change this value to
360 ohms.
