MOC3020XG

Triac, SCR Output Optoisolators Overview

The MOC3020XG is a single-channel optocoupler from Isocom Components, housed in a 6-pin DIP package. It features a Gallium Arsenide infrared LED input and a light-activated silicon bilateral triac output. Key electrical parameters include a maximum forward voltage of 1.65V, a peak repetitive reverse voltage of 400V for the triac, and an isolation voltage of 5300Vrms (7500V peak). The device operates without zero-crossing detection, allowing random phase triggering. Typical switching times are specified with a rise time of 2µs and a fall time of 11µs.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'XG' against the manufacturer's current ordering guide to confirm tape-and-reel packaging or specific binning requirements. Ensure the component matches the required voltage ratings for the target application. Cross-reference the datasheet revision date to confirm parameter validity. Confirm that the 6-pin DIP form factor fits the PCB layout constraints. Check for any regional compliance certifications listed in the official documentation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing switching. The high isolation voltage makes it suitable for noisy industrial environments. Consider the typical propagation delays if signal timing precision is critical. Verify that the input current limits align with the driving circuit capabilities. Ensure the thermal characteristics support the expected duty cycle of the AC load being controlled.

Triac, SCR Output Optoisolators Part Context

The MOC3020XG belongs to the MOC302x series of optically coupled isolators. This series typically includes variants such as MOC3020, MOC3021, MOC3022, and MOC3023, which may differ in gate trigger currents or voltage ratings. The 'XG' suffix likely denotes specific packaging or manufacturing options within the Isocom product line. These devices are designed for general-purpose AC switching applications requiring electrical isolation between control and power circuits.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other MOC302x series parts like MOC3020M or MOC3021M, provided pinout and electrical ratings match. Verify that alternative components support random phase operation if zero-crossing variants are considered. Ensure the replacement maintains the 5300Vrms isolation rating. Check for equivalent DIP-6 package dimensions to ensure mechanical compatibility.
