Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact package variant and tape/reel specifications. Ensure the procurement documentation explicitly references the 3750Vrms isolation rating and the 20% minimum CTR requirement. Confirm compliance with relevant safety certifications such as UL or CSA if required for the end application. Cross-reference the datasheet revision date to ensure parameter consistency.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required in a compact surface-mount footprint. The 80V collector-emitter voltage rating supports standard logic level interfacing. Consider the 20% minimum CTR for low-drive applications. Verify that the SOIC-8 thermal characteristics meet the system's dissipation requirements. Ensure the operating temperature range aligns with the environmental conditions of the target installation.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-200 belongs to the LTV series of optocouplers from Lite-On Inc., designed for general-purpose isolation tasks. It shares architectural similarities with single-channel variants like the LTV-817 but offers dual isolation paths. The series utilizes standard GaAs LED technology for reliable long-term operation. This model serves as a cost-effective solution for applications requiring multiple isolated channels without increasing board space significantly.
