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. They are
designed for use with a triac in the interface of logic systems to equipment powered from 115/240 VAC lines,
such as solid-state relays, industrial controls, motors,
solenoids and consumer appliances, etc.
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.

As per IEC 60747-5-2, this optocoupler is suitable for “safe electrical insulation” only within the safety limit data.
Compliance with the safety ratings shall be ensured by means of protective circuits.
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

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
is calculated so that I

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.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,
under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts.
Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failedapplications,
and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of
counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are
listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have
full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technicalandproduct information.
Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide
any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our
customers to do their part in stopping this practice by buying direct or from authorized distributors.
