Forward current transfer ratio
WebJul 14, 2013 · The current transfer ratio of a common base stage is 1 at first approximation. The emitter current (the input) is the collector current (the output) plus the base current. But the ratio of collector current to base current is the gain of the transistor. WebSep 1, 2024 · The current transfer ratio (CTR) is the ratio between the LED and sensor currents, effectively gaining the device and reflecting its efficiency. Opto-isolators with a low CTR will require more current to drive the LED to create sufficient current at the phototransistor for a particular output load.
