Abstract
An optocoupler includes a light output chip and a light-sensing chip. A light-receiving surface of the light-sensing chip is disposed to face a light output surface of the light output chip. The light-sensing chip and the light output chip are a green light-emitting diode and a blue light-emitting diode, respectively. Accordingly, the optocoupler has a stable output performance at a working temperature ranging from −55° C. to 150° C. and a high response frequency.
