MOC3021 is an optically isolated triac driver device. This device contains 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 115/230 VAC operations. The IC will provide electrical isolation between High voltage side and the Low voltage side.
• Excellent IFT stability: IR emitting diode has low degradation
• High isolation voltage: minimum 5300 VAC RMS
• Underwriters Laboratory (UL) recognized
• Peak blocking voltage: 400V-MOC3021
• VDE recognized
