  • What is the current transfer ratio? | Toshiba Electronic

    The current transfer ratio (CTR) refers to the ratio of the collector current at the output side I c to the input current passed to the LED at the input side I F expressed as a percentage. It is defined by the following formula. CTR=(I C /I F)×100 (%) As is the case with hFE for transistors, the current transfer ratio is an important parameter for transistor-output photocouplers.
