WebApr 11, 2024 · If CTR is 50% then the LED needs 140mA to get 70mA without saturation. In saturation the CTR is lower. The datasheet only shows LED current in saturation up to 60mA, and already CTR is less than 50% of nominal (ie. <30mA out when CTR is 50%). You won't get 70mA from this optocoupler. WebThis is a minimum value expressed as a percentage of the input current. Typical CTR specs are around 10-50%; these devices operate similarly to step-down isolation transformers. Optocouplers designed to step-up current into the output circuit, often those with photodarlington outputs, can reach 600% or more. dialog box stuck behind windowWebTransistor Output Optocouplers are available at Mouser Electronics.
