MOC3063M Datasheet, PDF (7/11 Pages) Fairchild Semiconductor – The MOC306XM and MOC316XM devices consist of a GaAs infrared emitting diode optically coupled to a monolithic silicon detector performing the function of a zero voltage crossing bilateral triac driver.

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. t_RC 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.
V_CC
R_in is calculated so that I_F is equal to the rated I_FT
of the part, 15mA for the MOC3061M, 10mA for
the MOC3062M, or 5mA for the MOC3063M.
The 39Ω resistor and 0.01µF 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; resistors, R1 and R2, are
optional 330Ω.
Note:
This optoisolator should not be used to drive
a load directly. It is intended to be a trigger
device only.
