Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official datasheet DS70-2012-0048 to confirm package type and tape/reel specifications. Ensure that the required current transfer ratio (CTR) bin matches the design requirements, as values can vary within the specified 130% to 260% range. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and SMD form factor are required for single-channel DC signal transmission. Consider the 80 V collector-emitter voltage limit and 50 mA maximum current constraints for load driving capabilities. Evaluate the thermal management needs given the 200 mW power dissipation rating and extended operating temperature range up to 110°C for robust performance in industrial environments.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-816S-B belongs to the LTV-816 series of photocouplers produced by Lite-On. This series includes various channel configurations such as the dual-channel LTV-826 and quad-channel LTV-846. The 'S' designation typically indicates a surface-mount package variant, distinguishing it from through-hole DIP versions like the standard LTV-816. The series is widely recognized for its reliability in general electronic applications requiring electrical isolation.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other LTV-816 series variants with matching SMD packages, provided their CTR and voltage ratings meet or exceed the original specifications. Cross-reference with equivalent transistor-output optocouplers from other manufacturers ensuring identical 5000 Vrms isolation and similar electrical characteristics.
