Datasheet MOC3043M, MOC3042M, MOC3032M, MOC3031M, MOC3041M Datasheet (Fairchild Semiconductor)

DESCRIPTION

The MOC303XM and MOC304XM devices consist of a AlGaAs
infrared emitting diode 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
teletypewriters, CRTs, solid-state relays, industrial controls,
printers, motors, solenoids and consumer appliances, etc.

APPLICATIONS

• Static power switches • AC motor drives

• Temperature controls • E.M. contactors

• AC motor starters • Solid state relays

FEATURES

• Simplifies logic control of 115 VAC power

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. τRC is measured at this point and
recorded.

Typical circuit (Fig 12, 13) 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

is calculated so that IFis equal to the rated IFTof the part, 5 mA for the MOC3033M and MOC3043M, 10 mA for the MOC3032M
and MOC3042M, or 15 mA for the MOC3031M and MOC3041M. 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.

Suggested method of firing two, back-to-back SCR’s with a Fairchild triac driver. Diodes can be 1N4001; resistors, R1 and R2, are
optional 1 k ohm.
