MOC3011SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3011SR2VM is a random-phase triac driver optocoupler manufactured by Fairchild Semiconductor. It features a single channel with an AlGaAs infrared emitting diode and a light-activated silicon bilateral switch. The device provides electrical isolation of 4170 Vrms for surface-mount applications in a 6-SMD package. It is designed to interface electronic controls with power triacs for resistive and inductive loads operating at 115/240 VAC. Key parameters include a maximum forward current of 60 mA, a forward voltage of 1.15 V, and a minimum on-state peak voltage of 250 V.

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entity, onsemi, when sourcing this component. Confirm that the specific suffix SR2VM corresponds to the surface-mount 6-pin configuration and the 4170 Vrms isolation rating. Ensure compatibility with standard surface-mount assembly processes. Cross-reference datasheets from authorized distributors to confirm current production status and availability, as manufacturing rights may have transferred.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring random-phase triggering of triacs in AC power circuits. It is suitable for interfacing low-power logic signals with higher-power triac gates. Consider the 4170 Vrms isolation voltage for safety requirements. Evaluate the 60 mA forward current capability against the driving circuit's output. Ensure the 250 V minimum on-state peak voltage meets the load requirements. Verify the surface-mount package dimensions fit the PCB layout constraints.

Triac, SCR Output Optoisolators Part Context

The MOC3011SR2VM belongs to the MOC301XM series of random-phase optoisolators. This family includes variants like the MOC3010M and MOC3012M, differing primarily in trigger sensitivity and packaging. These devices are widely used in industrial and consumer electronics for AC power switching. The series is characterized by its ability to drive triacs at any point in the AC cycle, offering flexibility in phase-control applications compared to zero-crossing devices.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes within the same family include the MOC3010SVM and MOC3012SVM, which share similar pinouts and isolation characteristics but may differ in gate trigger current sensitivity. Verify that any replacement maintains the 4170 Vrms isolation rating and surface-mount form factor. Consult official substitution guides from onsemi/Fairchild for confirmed equivalent part numbers.
