See equation 2. Combining equation 2 with the transistor current gain, hFE, provides a more complete optocoupler gain equation: The relationship given in equati on 3 can be shown in a block diagram of the four elements that make up the DC transfer function of the phototransistor coupler. These elements are shown in figure 3. fish stick funnyWebAug 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. fishstick from fortnite
