The transistor-output optocoupler pairs an infrared LED with a silicon phototransistor to achieve full galvanic isolation between input and output. It offers complete CTR rankings, low leakage current and high withstand voltage, and is widely used in switching power supplies, inverters, home appliance control boards and industrial control systems.

DIP and SOP packages are available, together with tape-and-reel packing and custom CTR binning services on request.
