Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TA' confirms tape-and-reel packaging rather than cut tape or tube. Ensure the datasheet revision matches the required current transfer ratio specifications. Confirm RoHS compliance status if environmental regulations apply. Check lead times as availability may vary by distributor. Validate pinout compatibility with existing PCB footprints before ordering.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Choose this component when multiple isolated channels are needed in a single package. Consider the 5000 Vrms isolation for high-voltage separation needs. Evaluate the 4 µs/3 µs switching speeds against system timing requirements. Compare current transfer ratios with other Lite-On series like LTV-816S for single-channel alternatives. Ensure the surface-mount form factor fits the assembly constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

Part of the LTV-8x6 series including LTV-816S (single), LTV-826S (dual), and LTV-846S (quad). All share similar electrical characteristics and isolation ratings. The series is designed for general-purpose optoisolation in industrial and consumer electronics. Commonly used in applications requiring reliable signal transmission across isolation barriers.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations
