Opto coupler ctr
Did you know?
WebThe Current Transfer Ratio (CTR) is an electrical parameter of an optocoupler. CTR, as a percen tage, is defined as the ratio of the output collector current (IC) caused by the light … 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.

Hi. we are using this circuit for getting a feedback of AC mains to MCU. this is a mass produced circuit. the problem is that sometimes the opto-coupler CTR decreases so fast in couple of months and makes the circuit malfunction. I have searched and know about CTR degradation with time and its … 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.
