LOC112

Transistor, Photovoltaic Output Optoisolators Overview

The LOC112 is a single linear optocoupler manufactured by Littelfuse. It features an infrared LED optically coupled with two photodiodes, where one feedback photodiode generates a control signal for the input LED to ensure high linearity. Key electrical characteristics include a typical total harmonic distortion (THD) of -87dB and a broadband frequency response exceeding 200 kHz. The device offers 0.01% servo linearity and high gain stability. It operates within a temperature range of -40°C to +85°C with a power dissipation rating of 500 mW.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific package variant and ordering suffix when sourcing, as Littelfuse may offer different pin configurations or tape-and-reel options. Confirm that the component meets VDE safety standards if used in isolated applications. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability. Check for any recent product lifecycle notices regarding availability or replacement recommendations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high linearity and wide bandwidth are critical requirements for signal isolation. The internal feedback mechanism makes it suitable for applications demanding low distortion compared to standard digital optocouplers. Consider the thermal management capabilities given the 500 mW power dissipation limit. Ensure the isolation voltage rating aligns with the system's safety requirements.

Transistor, Photovoltaic Output Optoisolators Part Context

The LOC112 belongs to Littelfuse's Linear Optocouplers series, designed specifically for analog signal transmission rather than simple on-off switching. This series utilizes advanced optical coupling techniques to maintain signal integrity over isolation barriers. It serves as a specialized solution for industries requiring precise data transfer between isolated domains.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate generic linear optocouplers from other manufacturers only if they match the dual-photodiode feedback architecture and bandwidth specifications.
