MOC3012FM

Triac, SCR Output Optoisolators Overview

The MOC3012FM is a Triac and SCR output optocoupler manufactured by onsemi. It features a random phase triac driver output without zero-crossing circuitry, housed in a 6-SMD package. Key electrical parameters include an isolation voltage of 7500 Vpk, a forward current (If) of 60 mA, and a forward voltage (Vf) of 1.15 V. The device supports a maximum power dissipation of 330 mW and operates within a temperature range of -40°C to +85°C. It has a peak off-state voltage (VDRM) of 250 V and a maximum trigger current of 5 mA.

Triac, SCR Output Optoisolators Feature Summary

• Integrates a GaAs infrared emitting diode with a light-activated silicon bilateral switch for robust signal isolation.
• Provides random phase triggering capability, allowing control at any point in the AC waveform cycle.
• Offers high insulation voltage to ensure safety between input and output circuits.

Triac, SCR Output Optoisolators Applications

• Solid-state relay drivers
• AC motor speed control
• Lighting dimmer applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'FM' corresponds to the 6-SMD surface mount package variant rather than the through-hole DIP versions. Confirm that the 7500 Vpk isolation rating aligns with system safety requirements. Check RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase firing is required for AC load control. Ensure the 250 V off-state voltage rating exceeds the peak line voltage. Verify that the 6-SMD footprint fits the PCB layout constraints compared to alternative DIP packages.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC301x series of Triac output optoisolators from onsemi. It is designed for general-purpose AC switching applications where galvanic isolation is necessary. The family includes variants with different packaging options such as DIP and SMD.

Triac, SCR Output Optoisolators Replacement Considerations

Consider MOC3012SR2M for similar SMD functionality with potentially different isolation ratings. MOC3012M serves as a through-hole equivalent if board space allows for DIP packaging changes.
