Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only. TA = 25°C unless otherwise specified.

Notes:
1. Test voltage must be applied within dv/dt rating.
2. This is static dv/dt. See Figure 11 for test circuit. Commutating dv/dt is a function of the load-driving thyristor(s) only.
3. All devices are guaranteed to trigger at an IF value less than or equal to max IFT. Therefore, recommended operating
IF lies between max IFT (15 mA for MOC3081M, 10 mA for MOC3082M, 5 mA for MOC3083M) and absolute
maximum IF (60 mA).
4. Isolation voltage, VISO, is an internal device dielectric breakdown rating. For this test, pins 1 and 2 are common, and
pins 4, 5 and 6 are common.

MOC3081M, MOC3082M, MOC3083M — 6-Pin DIP Zero-Cross Triac Driver Optocoupler (800 Volt Peak)
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 MOC3081M, 10 mA for the MOC3082M,
and 5 mA for the MOC3083M. The 39 Ω 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 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 Ω.
Note: This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only.
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 RTEST 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.
