MOC3011VM

Triac, SCR Output Optoisolators Overview

The MOC3011VM is a single-channel Triac Output Optocoupler featuring a random-phase triac driver output. It provides electrical isolation between control circuits and power triacs for resistive and inductive loads in 115/240 VAC operations. The device incorporates an AlGaAs infrared emitting diode and a light-activated silicon bilateral switch. Key parameters include a maximum forward current of 60 mA, a nominal input trigger current of 10 mA, and an off-state peak voltage of 250 V. It offers an isolation voltage of 5300 Vrms and operates within a temperature range of -40 °C to +85 °C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'VM' against official Fairchild or onsemi documentation to confirm package type and compliance status. Check for obsolete status or lifecycle notices, as earlier variants like MOC3011M are marked discontinued. Ensure the component matches the required isolation voltage and pin configuration for the target application design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing switching. Verify that the 250 V off-state voltage rating meets the peak line voltage requirements of the load circuit. Confirm compatibility with the driving logic levels and ensure the thermal dissipation capabilities support the expected duty cycle and ambient operating conditions.

Triac, SCR Output Optoisolators Part Context

The MOC3011VM belongs to the MOC301XM series of 6-pin DIP random-phase optoisolators. This family includes variants such as MOC3010M, MOC3012M, and MOC302XM. These devices are standardized for general-purpose AC power control applications, offering reliable optical isolation and stable trigger characteristics across the specified temperature range.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Cross-reference with MOC3011MS or MOC3011M_Q only if datasheet specifications match exactly, noting potential differences in packaging or obsolescence status.
