• Integrated triac output for direct AC load driving
• High isolation voltage for enhanced safety
• Compliant with international safety certifications

Triac, SCR Output Optoisolators Applications

• Solid-state relays (SSRs)
• AC motor speed controllers
• Lighting dimmer circuits
• Heater control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TVM' corresponds to the 6-DIP package configuration as documented by onsemi. Confirm that the non-zero-crossing characteristic aligns with your noise immunity requirements, as this may generate higher EMI compared to zero-crossing variants. Ensure compliance with RoHS3 standards if required by your manufacturing process.

Triac, SCR Output Optoisolators Selection Notes

Select this component when phase-angle control is necessary rather than simple on/off switching. The non-zero-crossing feature allows for smoother control of inductive loads but requires careful PCB layout to manage electromagnetic interference. Compare against zero-crossing models like MOC306x if noise reduction is the primary constraint, noting the trade-off in control precision.

Triac, SCR Output Optoisolators Part Context

Part of the MOC series, widely used in industrial automation and consumer electronics for AC power switching. The MOC3072 variant specifically targets applications requiring immediate response to trigger signals without waiting for the AC sine wave zero crossing, offering faster turn-on times.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes must match the 6-pin DIP package, 4170Vrms isolation, and non-zero-crossing triac output characteristics. Verify pinout compatibility and thermal resistance ratings before substitution to ensure circuit integrity.
