DESCRIPTION
The CNY64, CNY65, and CNY66 consist of a
phototransistor optically coupled to a gallium arsenide
infrared-emitting diode in a 4 pin plastic package.
The single components are mounted opposite one another,
providing a distance between input and output for highest
safety requirements of > 3 mm.

APPLICATIONS
Circuits for safe protective separation against electrical
shock according to safety class II (reinforced isolation):
• for appl. class I to IV at mains voltage ≤ 300 V
• for appl. class I to IV at mains voltage ≤ 600 V
• for appl. class I to III at mains voltage ≤ 1000 V according
to DIN EN 60747-5-5 (VDE 0884-5), suitable for:
- Switch-mode power supplies
- Line receiver
- Computer peripheral interface
- Microprocessor system interface

FEATURES
• Rated recurring peak voltage (repetitive)
VIORM = 1450 Vpeak
• Thickness through insulation ≥ 3 mm
• Creepage current resistance according to
VDE 0303 / IEC 60112 comparative tracking
index: CTI ≥ 200
• Material categorization: for definitions of compliance
