MOC3012FVM

Triac, SCR Output Optoisolators Overview

The MOC3012FVM is a random phase triac driver output optocoupler manufactured by onsemi. It features a PhotoTriac output and operates without a zero-crossing circuit, allowing for phase-angle control applications. The device is housed in a 6-pin surface-mount package (SMD) and provides high isolation voltage of 7500Vpk between input and output circuits. Key electrical parameters include a maximum off-state voltage of 250 V, a forward current of 60 mA, and a peak repetitive off-state voltage rating suitable for low-voltage AC line applications.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triggering capability enables precise phase-angle control of AC loads without requiring zero-crossing detection.

Triac, SCR Output Optoisolators Applications

• Phase-angle control for resistive or inductive AC loads
• Solid-state relay drivers for low-power AC switching
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify component status as the MOC3012FVM is listed as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the specific surface-mount package variant matches the design requirements, as pinout and thermal characteristics differ from through-hole versions. Cross-reference datasheets to confirm insulation voltage ratings and package dimensions before finalizing procurement plans.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required for AC load control rather than zero-crossing switching. Consider the 250 V off-state voltage limit for appropriate load matching. Evaluate the surface-mount packaging constraints against PCB layout requirements. Compare isolation voltage specifications with system safety standards to ensure adequate creepage and clearance distances are maintained in the final design.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3012M series of triac and SCR output optocouplers. It shares functional similarities with other devices in the family but differs in packaging and specific electrical ratings. The FVM suffix typically denotes a specific surface-mount package configuration distinct from the standard DIP variants found in the same product line.

Triac, SCR Output Optoisolators Replacement Considerations

Direct replacements may be limited due to the obsolete status. Verify compatibility with alternative random-phase triac driver optocouplers such as the MOC3011 series or similar devices from other manufacturers, ensuring matching voltage ratings, isolation levels, and package footprints.
