(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.

1. Test voltage must be applied within dv/dt rating.

2. All devices are guaranteed to trigger at an I F value less than or equal to max I FT . Therefore, recommended operating I F lies between I FT

2. (15 mA for MOC3041, 10 mA for MOC3042, 5 mA for MOC3043) and absolute max I F (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.

R TEST

R = 10 k W

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 R TEST 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. 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.

R in is calculated so that I F is equal to the rated I FT 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 m F

capacitor are for snubbing of the triac and may or may not

be necessary depending upon the particular triac and load

used.
