LOC112P

Transistor, Photovoltaic Output Optoisolators Overview

The LOC112P is a single linear optocoupler manufactured by Littelfuse. It integrates an infrared LED with two photodiodes for precise signal transmission. The device provides high isolation voltage, rated at 650 V continuous between collector-emitter and collector-grating terminals across temperatures from 25°C to 175°C. One photodiode serves as a feedback input to generate control signals, ensuring accurate linearity. The component utilizes an 8-SMD gull-wing package suitable for surface mount applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'G' against official Littelfuse documentation to confirm availability and compliance. Confirm that the 8-SMD gull-wing package matches the target PCB footprint. Ensure the supplier provides valid traceability for the component's origin and handling conditions prior to purchase.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when linear optical isolation is required rather than digital switching. The dual photodiode architecture supports feedback mechanisms for enhanced accuracy. Verify thermal ratings align with the operating environment, specifically the 175°C junction temperature limit. Ensure the 650V isolation rating meets the safety requirements of the target application.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LOC series of linear optocouplers from Littelfuse. These devices are designed for applications demanding high linearity and stability. The series typically features robust isolation characteristics and compact surface-mount packaging. The LOC112P represents a specific configuration within this family optimized for feedback-controlled linear transmission.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Consult official Littelfuse substitution guides for verified alternatives. Generic optocouplers may not match the specific dual-photodiode feedback architecture or the 650V isolation rating. Ensure any substitute maintains the 8-SMD gull-wing form factor and linear performance characteristics.
