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

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, 15mA for the MOC3081M, 10mA for the MOC3082M,
and 5mA for the MOC3083M. The 39 ? resistor and 0.01μF capacitor are for snubbing of the triac and may or may not
be necessary depending upon the particular triac and load use.

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 330 ? .
Note: This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only.
