LOC111P

Transistor, Photovoltaic Output Optoisolators Overview

The LOC111P is a single linear optocoupler manufactured by Littelfuse Inc. It features an infrared LED optically coupled with two photodiodes, where one feedback photodiode generates a control signal for high linearity. Key specifications include 0.01% servo linearity, typical Total Harmonic Distortion (THD) of -87dB, and a broadband frequency response exceeding 200 kHz. The device offers high gain stability, low input-to-output capacitance, and low power consumption while supporting the coupling of both analog and digital signals.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High linearity performance with minimal distortion
• Broadband frequency capability for fast signal transfer
• Integrated feedback mechanism for gain stability

Transistor, Photovoltaic Output Optoisolators Applications

• Precision analog signal isolation
• Feedback loop control systems
• Industrial automation sensing

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'P' against the manufacturer's current datasheet to confirm package type and tape/reel configuration. Ensure the component meets VDE compatibility requirements if isolation standards are critical for your application. Cross-reference part numbers carefully as Littelfuse may update designations or supersede older IXYS-branded inventory.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when precise analog signal transmission across isolation barriers is required. The integrated feedback photodiode distinguishes it from standard digital optocouplers, making it suitable for applications demanding high accuracy and low harmonic distortion. Consider the >200 kHz bandwidth requirement and low power constraints during circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

The LOC111 series belongs to Littelfuse's portfolio of linear optocouplers, designed for high-performance isolation. Originally associated with IXYS Integrated Circuits before Littelfuse's acquisition, these devices utilize dual photodiode technology to achieve superior linearity compared to conventional single-diode isolators.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes should be sought within the same linear optocoupler family. Verify pinout compatibility and electrical parameters such as CTR and bandwidth when considering alternative manufacturers. Check Littelfuse MROplus resources for official cross-references.
