關於 光耦合器/光電耦合器
光耦合器利用發光輸入端與光敏輸出端,在電氣隔離屏障兩側傳遞訊號,可隔離接地、阻斷雜訊路徑、保護低電壓控制電路,並在危險電壓區域之間提供回授。常用於電源供應器、工業控制、馬達驅動、通訊設備、家電及汽車系統。輸出結構包括光電晶體、光達林頓、邏輯閘、光伏、光控SCR或雙向可控矽及線性類比型,各自適用於不同速度、增益和負載需求。
選型時應確認隔離電壓、工作電壓、爬電距離與電氣間隙、絕緣等級、通道數、輸入正向電流及輸出類型。光電晶體型需比較電流傳輸比(CTR)、CTR分檔及老化裕量;數位型則應確認資料速率、傳播延遲、脈寬失真、抖動和共模瞬態抗擾度。還需核對輸出電壓與電流、切換特性、溫度範圍、封裝、安全認證,以及基本或加強絕緣要求。腳位相似不代表隔離、CTR、速度或法規適用性相同。
