The QCK6 product consists of a infrared light emitting diode coupled to an NPN silicon photodarlington packaged in a metal housing. The package is designed for surface mount applications where extreme temperatures are experienced during solder reflow. The gap between emitter and detector side is 4mm wide and the leads are formed to sit flush on the PCB during solder reflow.
