Optocouplers (photocouplers) provide galvanic isolation between high-voltage and low-voltage circuits, protecting sensitive control logic from transients, noise, and ground faults — critical in industrial motor drives, power supplies, PLC inputs, medical equipment, and telecom systems. Our inventory includes transistor output, logic output, Darlington output, and high-speed optocouplers from Broadcom (HCPL/ACPL series), Toshiba (TLP series), ON Semiconductor (FOD series), Vishay, and Lite-On, with isolation voltages up to 5000 Vrms and data rates from DC-coupled to 25 Mbps.
Many industrial legacy systems rely on older optocoupler part numbers (such as PC817, 4N25, 4N35, CNY17) that are still in production but frequently face supply shortages due to the volume of sustaining designs. Welllinkchips stocks popular and difficult-to-find optocoupler variants, including SMD packages and high-CMR (common-mode rejection) versions for demanding industrial applications.
