MOC3061FVM

Triac, SCR Output Optoisolators Overview

The MOC3061FVM is a single-channel Triac and SCR output optocoupler manufactured by onsemi. It features an integrated zero-crossing detection circuit for low EMI switching of AC loads. The device utilizes a PhotoTriac output capable of blocking up to 600 V in the off-state. Electrical specifications include a maximum forward current of 60 mA, a forward voltage of 1.3 V, and a power dissipation rating of 250 mW. The unit provides high isolation with a rated insulation voltage of 5250 Vrms. It operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOP-6 package.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuit minimizes electromagnetic interference during AC load switching
• High isolation voltage capability ensures safe separation between control and power circuits
• PhotoTriac output designed for direct driving of triacs and SCRs in AC applications

Triac, SCR Output Optoisolators Applications

• Lighting dimmers and brightness control systems
• Motor speed controllers for AC motors
• Solid state relays (SSR) for single-phase AC switching
• General purpose AC power control modules

Triac, SCR Output Optoisolators Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Check for specific suffix variations that may indicate different packaging or tape-and-reel configurations. Ensure the supplier provides valid traceability records. Validate datasheet revisions match the production batch requirements.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC circuits. The 600 V blocking voltage suits standard residential and commercial line voltages. Consider the SOP-6 package for space-constrained PCB layouts. Verify thermal management needs against the 250 mW dissipation limit. Compare against non-zero-crossing variants if phase-angle control is needed instead.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3 series of Triac output optocouplers from onsemi. The family includes variants with different peak currents and package types. The MOC3061 specifically denotes the 0.6 A peak current class with zero-crossing functionality. It complements other series members like the MOC3021 which lacks zero-crossing detection.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes include MOC3061M and MOC3061TVM. These share identical electrical characteristics and pinouts. Verify package compatibility as MOC3061M uses PDIP while MOC3061TVM uses tube packaging. Cross-reference datasheets for minor parameter tolerances before substitution.
