MOC3061TM

Triac, SCR Output Optoisolators Overview

The MOC3061TM is a six-pin DIP zero-crossing phototriac driver optocoupler manufactured by Fairchild Semiconductor. It integrates a gallium arsenide infrared emitting diode with a monolithic silicon detector to provide electrical isolation between logic circuits and AC power loads. The device features an internal zero-voltage crossing circuit that minimizes electromagnetic interference during switching. It supports a peak off-state voltage of 600V and offers high dv/dt immunity, making it suitable for interfacing low-power logic systems with mains-powered equipment.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against the manufacturer's current product status, as this variant may be obsolete or discontinued. Confirm that the package type matches the required PCB footprint. Ensure the component meets all necessary safety certifications for the target application region before finalizing procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize noise in AC line applications. Compare the 600V peak off-state voltage against the load requirements. Consider the PDIP-6 package constraints and verify compatibility with existing logic interface voltages and currents.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC306x family of zero-crossing triac driver optocouplers. It is functionally similar to the MOC3061M and MOC3062M series, differing primarily in packaging or manufacturing lot specifications. These devices are designed for general-purpose AC power switching applications requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3061M is a documented equivalent within the same functional family. Verify pinout compatibility and insulation ratings before substitution. Other variants like MOC3062M offer different trigger sensitivities and should be evaluated based on specific drive requirements.
