Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix configuration against the official Toshiba datasheet to ensure compatibility with required packaging and lead times. Confirm that the zero-crossing feature aligns with application noise requirements. Check RoHS compliance status for regulatory adherence. Validate pinout compatibility if replacing existing components in a design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when low-noise AC switching is critical due to its integrated zero-crossing circuit. Ensure the 600 V off-state voltage rating exceeds the peak line voltage of the target application. Consider the 70 mA RMS current limit for load sizing. Verify that the SOP-6 package fits the PCB layout constraints compared to alternative packages like SOP-4.

Triac, SCR Output Optoisolators Part Context

This part belongs to the TLP266J series of photo-triac output optocouplers manufactured by Toshiba Semiconductor and Storage. The series is designed for general-purpose AC switching applications requiring galvanic isolation.
