MOC3022XG

Triac, SCR Output Optoisolators Overview

The MOC3022XG is a six-pin optically coupled isolator manufactured by Isocom Components 2004 LTD. It integrates a gallium arsenide infrared emitting diode with a light-activated silicon bilateral triac output. The device provides an isolation voltage of 5300Vrms and supports an off-state voltage rating of 400V. It operates as a non-zero-crossing triac driver with a single channel configuration. The maximum LED trigger current is specified at 10mA. The component is housed in a standard 6-DIP package measuring 7.62mm in width.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a gallium arsenide infrared emitter with a light-activated silicon bilateral triac for optical isolation
• Provides high electrical isolation capability rated at 5300Vrms between input and output circuits
• Features a non-zero-crossing triac output suitable for phase control applications requiring immediate triggering

Triac, SCR Output Optoisolators Applications

• Triac gate drive circuits for AC power control
• Solid state relay interfaces
• Phase angle firing control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific ordering suffix to ensure the correct package type, as variations such as surface mount or tape-and-reel formats exist within the MOC3022 family. Confirm RoHS compliance status if required for your assembly process. Cross-reference the manufacturer part number with official distributor catalogs to ensure availability of the exact DIP variant rather than alternative packaging options.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a non-zero-crossing triac driver is required for applications where precise phase control timing is critical. Ensure the load voltage does not exceed the 400V off-state rating. Verify that the system design accommodates the 10mA maximum LED trigger current requirements. Consider thermal management and isolation distance constraints relative to the 5300Vrms specification during PCB layout.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC302x series of optocouplers designed for controlling AC loads. Unlike zero-crossing variants, this model triggers immediately upon LED activation, making it distinct from other members of the family that delay conduction until the next AC voltage zero point. It serves as a direct interface between low-voltage logic circuits and high-voltage AC triacs.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes include the MOC3021M and MOC3023M from the same manufacturer, which share similar non-zero-crossing triac output characteristics. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure the replacement part matches the 6-DIP package dimensions for mechanical fit.
