Procurement Notes
Verify the specific suffix and tape/reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the 6-SMD gull-wing package dimensions match your PCB footprint requirements. Ensure the 5000Vrms isolation rating meets your safety compliance standards for the intended application environment.
Selection Notes
Select this component when a random phase Triac output is required for AC switching applications. Consider the surface mount form factor for space-constrained designs. Verify that the input current requirements align with your driving circuit capabilities and that the output voltage rating is sufficient for the load being controlled.
Part Context
Isocom Components 2004 LTD specializes in high-performance infrared optoelectronic devices, including optocouplers and optoswitches.
