EL357B EL357N(B)(TA)-G  是光电耦合器的一个型号，属于光电元件的一种,对电有良好的绝缘性,由于输入/输出端的信号是以“光”交连达成。简单说它是利用输入端部分的发光装置将电的信号转换成光的信号传送出,再由受光部分转换成电的信号。

EL357B EL357N(B)(TA)-G特性: 电流传输比(CTR:MIN.50% at IF=5mA,VCE=5V)。输入端与输出端之间的绝缘电压(Viso=3750Vrms )。无铅，符合RoHS要求。紧凑4针SOP封装。

EL357B EL357N(B)(TA)-G应用可编程控制器系统设备，测量仪器家用电器，如风扇加热器等监控和检测电路不同电位和阻抗的电路之间的信号传输

无卤素电流传输比（CTR：50〜600％，在IF =5mAVCE=5V）输入和输出之间的隔离电压
