The CQY80N(G) series consist of a phototransistor optically coupled to a gallium arsenide infrared emitting diode in a 6-lead plastic dual inline package. The elements are mounted on one leadframe using a coplanar technique, providing a fixed distance between input and output for highest safety requirements.
Circuits for safe protective separation against electrical shock according to safety class II (reinforced isolation):
● For appl. class I – IV at mains voltage ≤ 300 V
● For appl. class I – III at mains voltage ≤ 600 V according to VDE 0884, table 2, suitable for:
Switch-mode power supplies, line receiver, computer peripheral interface, microprocessor system interface.
