1. 100x scope probes are used, to allow high speeds and voltages.
2. 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 vernier resistor combined with various capacitor combinations 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.

BASIC APPLICATIONS
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 MOC3061-M, 10 mA for the MOC3062-M, or 5 mA for
the MOC3063-M. The 39 ohm resistor and 0.01 µF capacitor are
for snubbing of the triac and is often, but not always,
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;
VCC
resistors, R1 and R2, are optional 330 ohm.
Note: This optoisolator should not be used to drive a
load directly. It is intended to be a trigger device only.
