MOC306XM, MOC316XM — 6-Pin DIP Zero-Cross Phototriac Driver Optocoupler (600 Volt Peak)
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.
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 39
Ω
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 330
Ω
.
Note:
This optoisolator should not be used to drive
a load directly. It is intended to be a trigger
device only.
