The MOC301XM and MOC302XM series are optically
isolated triac driver devices. These devices contain a
GaAs infrared emitting diode and a light activated silicon
bilateral switch, which functions like a triac. They are
designed for interfacing between electronic controls and
power triacs to control resistive and inductive loads for
115 VAC operations.
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.

Note:
This optoisolator should not be used to drive a load directly. It is intended to be a trigger device only.
In this circuit the “hot” side of the line is switched and the load connected to the cold or ground side.
The 39Ω resistor and 0.01µF capacitor are for snubbing of the triac, and the 470Ω resistor and 0.05µF
capacitor are for snubbing the coupler. These components may or may not be necessary depending upon
the particular and load used.

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.
