WebSep 1, 2024 · Opto-isolators with a low CTR will require more current to drive the LED to create sufficient current at the phototransistor for a particular output load. The CTR is not constant but is dependent on the input current coming into the component. The CTR will also vary with each component, its temperature, and the component’s age, so it’s ...
