optical coupler
光耦合器
A sealed device containing an infraredemitting photodiode and a phototransistor. When current flows in the input circuit to the photodiode, light passes tot he phototransistor, turning it on and causing current to flow in the output circuit.
一种含有红外发射的光敏二极管和光敏三极管的密封器件。当电流在输入电路中通过光敏二极 管时，光通过光敏三极管，并启动光敏三极管，在输出电路中产生电流。 |
