The KB817 is a single-channel optocoupler (photo transistor type) designed for signal isolation between high- and low-voltage circuits. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a compact 4-pin dual in-line (DIP) package.
With an isolation voltage of 5000Vrms and a collector-emitter voltage (BVCEO) of 35V, this opto isolator ensures reliable electrical separation and noise immunity, making it ideal for industrial control systems and signal transmission applications.
