Opto coupler ctr
WebAug 27, 2024 · A: In simple terms, CTR indicates the efficiency of the optocoupler. If CTR is low, the input side will need more current drive to the LED in order to create sufficient current at the phototransistor for the output load. Higher CTR also provides some input/output margin as the LED ages.

For example if I have 2 different opto-couplers, first one has just 10% CTR (min) value while the second one has 1000% CTR (min) values. So when an opto-coupler has 1000% CTR then what parameter would be compromised in it with respect to another opto-coupler that has just 10% CTR value?

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.
