Triac, SCR Output Optoisolators Procurement Notes

Verify the obsolete status of this specific part number before finalizing designs, as it may no longer be in active production. Confirm that the 4-SMD Mini-Flat package dimensions match the target PCB footprint. Ensure that the absence of a zero-crossing feature aligns with the noise requirements of the specific application environment.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a non-zero-crossing Triac output is required for phase-angle control or general AC switching. Consider the 600V blocking voltage limit for line voltage applications. Evaluate the thermal performance of the Mini-Flat package under continuous RMS current conditions to ensure reliability within the specified operating temperature range.

Triac, SCR Output Optoisolators Part Context

This device belongs to the FODM30 series of Triac output optoisolators from onsemi. It is distinct from zero-crossing variants like the FODM306x series. The product is categorized under SCR/Triac output optocouplers, serving as a bridge between microcontroller logic and high-power AC systems.
