• Designed for surface-mount assembly using a compact six-pin gull-wing package.
• Ensures safety compliance through high dielectric strength insulation between input and output sections.

Triac, SCR Output Optoisolators Applications

• Solid-state relay driver circuits
• AC power switching applications
• Motor control systems requiring phase-angle control
• Industrial automation interface modules

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the surface-mount tape-and-reel packaging configuration. Ensure the non-zero crossing characteristic aligns with the application's noise immunity requirements, as this may generate higher electromagnetic interference compared to zero-crossing variants. Confirm that the 400 V blocking voltage meets the load specifications. Validate that the 6-pin SMD footprint matches the PCB design constraints.

Triac, SCR Output Optoisolators Selection Notes

Select this component when immediate triac turn-on is required without waiting for the AC waveform zero crossing. The non-zero crossing feature allows for precise phase-angle control but requires careful consideration of electromagnetic interference filtering. The surface-mount format suits automated assembly processes. Verify thermal management capabilities within the specified -40°C to 100°C operating range for the intended environment.
