LOC112S

Transistor, Photovoltaic Output Optoisolators Overview

The Littelfuse LOC112S is a single linear optocoupler featuring an infrared LED optically coupled with two photodiodes. One feedback photodiode generates a signal to linearize the input, while the second provides the output. Key electrical characteristics include a typical Total Harmonic Distortion (THD) of -87dB and a wide bandwidth exceeding 200 kHz. The device offers high gain stability and operates within a temperature range of -40°C to 85°C. It provides 3750Vrms isolation voltage and utilizes an 8-SMD package.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributor, as exemption details may vary by production batch. Confirm the specific suffix (e.g., -E, -F, -G) matches your packaging and regulatory requirements. Ensure the 8-SMD package footprint aligns with your PCB design constraints before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high linearity and low distortion are critical for signal integrity. The wide bandwidth supports applications requiring fast response times. Consider the operating temperature range and isolation voltage requirements relative to your system's environmental conditions and safety standards. Verify pinout compatibility if replacing existing designs.
