MOC3163FR2VM

Triac, SCR Output Optoisolators Overview

The onsemi MOC3163FR2VM is a surface-mount Triac and SCR output optocoupler featuring an integrated zero-crossing detection circuit. It provides high isolation voltage of 7500 Vpk between input and output channels. The device utilizes a gallium arsenide infrared LED coupled to a photo-triac output, designed for driving AC loads with minimal electromagnetic interference. Key electrical parameters include a peak off-state voltage (VDRM) of 600 V, a maximum forward current (If) of 60 mA, and a typical forward voltage (Vf) of 1.3 V. It operates within a temperature range of -40°C to +85°C and is housed in a compact 6-SMD Gull Wing package.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuitry for reduced electromagnetic interference during switching
• High isolation capability with 7500 Vpk dielectric strength between input and output
• Surface-mount 6-SMD Gull Wing package design for automated assembly

Triac, SCR Output Optoisolators Applications

• Motor speed control circuits
• Lighting dimmer applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'FR2VM' against the manufacturer's current datasheet to confirm active status and pinout compatibility. Check for recent product lifecycle notices as some variants may be obsolete or subject to change. Ensure the selected packaging matches the required reel specifications for surface-mount placement processes.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high-voltage isolation and low-noise AC switching are required in a surface-mount form factor. The integrated zero-crossing feature makes it suitable for applications sensitive to electrical noise. Compare the 600 V blocking voltage and 7500 V isolation rating against system requirements to ensure adequate safety margins for the intended AC line voltage.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC series of Triac and SCR output optocouplers from onsemi. It is functionally similar to through-hole variants like the MOC3163VM but offers a surface-mount footprint. The FR2VM suffix indicates specific tape-and-reel packaging and lead-free compliance, distinguishing it from tube-packaged equivalents.

Triac, SCR Output Optoisolators Replacement Considerations

Direct replacements include other MOC3163 series variants such as MOC3163VM (through-hole) or MOC3063SR2VM (random turn-on). Verify that the replacement maintains the same zero-crossing functionality and isolation voltage ratings if EMI reduction is critical.
