Application Background:


Optocouplers are optoelectronic devices that effectively isolate high-voltage and low-voltage circuits, ensuring circuit safety and stability. Optocouplers have wide-ranging applications, especially in situations that require signal isolation and transmission, such as power electronics, industrial automation, medical equipment, and communication devices.


Application Challenges:


In the application of Slkor optocouplers in the field of power electronics, signal transmission between high-voltage and low-voltage circuits has always been a challenging issue. Due to the significant potential difference between high-voltage and low-voltage circuits, direct connection can result in circuit short-circuits or damage. Therefore, optocouplers are necessary for signal isolation and transmission. However, the limited isolation voltage of optocouplers can cause interference, noise, or even circuit damage if the isolation voltage is insufficient. Therefore, in power electronics applications, optocoupler devices with high isolation voltage, good linearity, and fast transmission speed need to be selected to ensure signal transmission and isolation.


Solution:


The Slkor optocoupler SL-1007 is one of the devices in the SL-10XX series. The SL-10XX series devices consist of an infrared emitting diode and a photodetector, enclosed in a 4-pin SOP package. They are halogen-free and do not contain SbzO.
