The MOC3021 series are optically isolated TRIAC driver devices. These series 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. Applications: Solenoid/Valve controls Lighting controls Static power switches AC motor drives Temperature controls E.M contactors AC motor contactors Solid-state relay Programmable controllers Features/Specs: Storage Temperature Range: -40°C to +150°C Operating Temperature Range: -40°C to +85°C

• Non zero voltage crossing
• Isolation voltage between input and output (Viso：5300Vms)
