Product Description
The MOC3021 is a device that can drive a triac using optical isolation. It has a GaAs infrared diode that emits light and a silicon bilateral switch that acts like a triac when exposed to light. This device is meant to connect electronic controls and power triacs for controlling 115VAC resistive and inductive loads.
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: 400V-MOC3021
- VDE recognized (File #94766)
