DESCRIPTION
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.
FEATURES
• Excellent IFT stability—IR emitting diode has low degradation
• High isolation voltage—minimum 5300 VAC RMS
• Underwriters Laboratory (UL) recognized—File #E90700
• Peak blocking voltage
– 250V-MOC301XM
– 400V-MOC302XM
• VDE recognized (File #94766)
– Ordering option V (e.g. MOC3023VM)
APPLICATIONS
• Industrial controls
• Traffic lights
• Vending machines
• Solid state relay
• Lamp ballasts
• Solenoid/valve controls
• Static AC power switch
• Incandescent lamp dimmers
• Motor control

LOAD
GROUND
In this circuit the hotside of the line is switched and the load connected to the cold or ground side.
The 39 ohm resistor and 0.01µF capacitor are for snubbing of the triac, and the 470 ohm resistor and
0.05 µF capacitor are for snubbing the coupler. These components may or may not be necessary
depending upon the particular and load used.
