RENESAS 1 Channel SMD Optocoupler, 50mA, 2.5kV

The RENESAS 1 Channel SMD Optocoupler is a compact, surface-mount electronic component designed for reliable signal isolation. By utilising an internal light-emitting diode (LED) and a photodetector, it effectively transfers electrical signals between two isolated circuits while preventing high voltages from passing through. This makes it a crucial component for protecting sensitive low-voltage electronics from noise, spikes, or faults originating in high-voltage systems.

This 4-pin device offers robust performance with a maximum forward current (If Max) of 50mA and a high isolation voltage of 2.5kV, ensuring safe operation in demanding environments. With a minimum Current Transfer Ratio (CTR) of 50%, it provides efficient signal transmission. The collector-emitter breakdown voltage (V(br)ceo) is rated at 120V, offering a reliable buffer for the output side.

Its SMD (Surface-Mount Device) case style allows for streamlined, automated PCB (Printed Circuit Board) assembly, saving space and manufacturing time compared to through-hole alternatives. The compact design, with dimensions of just 43mm x 33mm x 15mm, is ideal for modern, high-density electronic designs where board real estate is at a premium.

This optocoupler is a fundamental building block in industrial control systems, power supplies, telecommunications equipment, and any application requiring safe, noise-free signal transfer across different circuit domains.
