群芯微 QX6N136 是一款性能卓越的單通道高速光耦合器，以下是其詳細介紹：
內部結構與工作原理
QX6N136 由一個 850nm 的 AlGaAs LED 光學耦合到一個高速光電檢測器組成。當輸入側的 LED 正向偏置時，會發出紅外光，該光線照射到輸出側的光電檢測器上，使光電二極管產生光電流，進而控制輸出晶體管的導通與截止，從而實現電信號的隔離傳輸。光電二極管偏置和輸出晶體管集電極的單獨連接，可以通過降低基極集電極電容，使速度比傳統光電晶體管耦合器提高 100 倍。
The QX6N136 consists of an 850nm AlGaAs LED optically coupled to a high-speed photodetector. When the LED on the input side is forward-biased, it emits infrared light, which illuminates the photodetector on the output side, so that the photodiode generates photocurrent, and then controls the on-off of the output transistor, so as to realize the isolated transmission of the electrical signal. The photodiode bias and separate connection of the output transistor collector can increase speeds by up to 100 times over conventional phototransistor couplers by reducing base collector capacitance.
