Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'C' corresponds to the required tape and reel packaging configuration as defined by Lite-On. Confirm that the 4-SMD gull-wing footprint matches the target PCB layout dimensions. Ensure compliance with RoHS directives if required by the end product specifications. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or moisture sensitivity levels prior to assembly.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface-mount solution is required for galvanic isolation. The 5000Vrms isolation rating makes it suitable for applications requiring robust separation between low-voltage logic and higher-voltage loads. Consider the 50mA output current capability for driving small relays or transistors. The wide temperature range supports operation in demanding environmental conditions where standard commercial-grade parts may fail.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LTV-8x7 series of transistor output optocouplers manufactured by Lite-On Technology Corporation. The series is designed for general-purpose isolation tasks. The 'S' designation indicates the surface-mount variant, while 'TA1' specifies the specific package type and lead finish. The 'C' suffix typically denotes the tape and reel packaging format for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements within the same family include LTV-817S-TA1 and LTV-817S-TA1-A-G. Verify pinout compatibility and electrical parameter equivalence before substitution. Other manufacturers offer pin-compatible alternatives such as the PC817 series, but isolation ratings and CTR ranges must be compared against the original specifications.
