MOC3063VM

Triac, SCR Output Optoisolators Overview

The MOC3063VM is a zero-crossing triac driver optocoupler from onsemi, featuring a single channel with a photo-triac output. It provides electrical isolation via an internal LED and phototriac structure. Key parameters include a maximum forward voltage of 1.5V, a maximum input current of 60 mA, and an isolation voltage of 7.5 kVrms. The device supports a peak off-state voltage (VDRM) of 600V and operates within a temperature range of -40°C to 85°C. It utilizes a 6-pin DIP package for through-hole mounting.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'VM' against the manufacturer's latest datasheet to confirm pinout and packaging configuration. Ensure that the required isolation voltage ratings meet the safety standards of the target application environment. Cross-reference the operating temperature range with system thermal constraints before finalizing component selection.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC line applications. Compare the 600V VDRM rating against the peak line voltage to ensure adequate margin. Consider the 7.5 kVrms isolation capability for safety compliance requirements in mains-connected designs.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3 series of zero-crossing triac drivers. It is designed for general-purpose AC power control applications where low EMI is critical. The device replaces older discrete isolation solutions by integrating the driver and isolation barrier into a single compact package.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other zero-crossing triac drivers with similar voltage ratings and pinouts, such as the MOC3061 or MOC3062 series, provided the trigger current characteristics are compatible with the design.
