MOC3012X

Triac, SCR Output Optoisolators Overview

The MOC3012X is a single-channel optoisolator manufactured by Isocom Components 2004 LTD, designed for AC load control applications. It features a Triac output topology with non-zero crossing detection capabilities. The device provides galvanic isolation of 5300Vrms between the input and output circuits. It is housed in a standard 6-DIP package with a pin spacing of 7.62mm (0.300 inches). Key electrical parameters include a typical forward voltage of 1.2V for the input LED and a hold current up to 100µA for the output Triac. The component supports a maximum voltage of 250V.

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific part number matches the required non-zero crossing variant, as this distinguishes it from zero-crossing models within the same series. Confirm the 6-DIP package dimensions align with the PCB footprint requirements. Ensure compliance with relevant safety certifications such as UL or VDE if the end application mandates certified isolation components. Check for RoHS compliance status based on the manufacturing batch date.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing operation is necessary to avoid phase delay issues in specific AC control scenarios. Consider the 5300Vrms isolation rating for high-noise industrial environments. Evaluate the 250V voltage rating against the peak line voltage of the target application. Compare the 100µA hold current requirement with the minimum load current to ensure reliable latching during operation.
