onsemi DC Input Optocoupler 1.65V Through Hole 6-Pin PDIP CNY173M

The onsemi CNY173M is a DC input optocoupler designed for industrial and electronic control circuits, featuring reliable signal isolation and robust performance. Its compact 6-Pin PDIP package suits PCB integration, and Through Hole mounting simplifies assembly.

This optocoupler achieves secure isolation via optical transfer, with a high isolation voltage of 7.5kVrms to protect sensitive electronics from transient voltages and electrical noise. Its maximum forward voltage of 1.65V enables integration into low-voltage signaling, while the maximum input current of 60mA supports a wide range of control applications.

Featuring both a typical rise time of 4μs and fall time of 3μs, the CNY173M assures quick signal response for timing-critical circuits. With a wide operating temperature range of -40°C to 100°C, it is the ideal choice for demanding environments such as laboratory instrumentation, manufacturing automation, HVAC systems, and commercial electronics.

Its current transfer ratio ranges from 100% up to 200%, allowing effective signal amplification and ensuring efficient operation even under varying load conditions. The device complies with IEC, EN, and UL standards, supporting safety and regulatory requirements across industrial and laboratory installations.

The Optocoupler comes packaged in tubes, simplifying bulk handling and storage for assembly lines. It is not automotive-standard, focusing instead on general industrial, laboratory, and commercial electronic applications where robust optical isolation and secure signal transfer are required.

Typical use cases include signal isolation in PLCs, microcontroller interfaces, sensor-to-processing unit assembly, and protection of measurement/control electronics against high-voltage surges.
