MOC3063 Optocoupler Overview:
Overview:
The MOC3063 is an optocoupler device that integrates a light-emitting diode (LED) and a phototriac in a single package. It is commonly used for isolating high-voltage circuits from low-voltage components while allowing for signal communication through light.
Parameters:
- Isolation Voltage: Voltage rating that specifies the maximum isolation capability between input and output.
- Trigger Current: Current required to activate the optocoupler.
- Response Time: Time taken for the optocoupler to switch on/off in response to input signals.
- Operating Temperature Range: Range of temperatures within which the optocoupler functions reliably.
- Package Type: Physical form factor and pin configuration of the device.
