Vishay Telefunken
¾GaAs Infrared Emitting Diode in Miniature (T– )
Package
Description
CQY37N is a standard GaAs infrared emitting diode in
a miniature top view plastic package.
Its clear lens provides a high radiant intensity without
external optics.
The diode is case compatible to the BPW17N photo-
transistor, allowing the user to assemble his own
optical interrupters.
