Optocoupler, Phototransistor Output, Very High Isolation Voltage
DESCRIPTION
The CNY651 Series are high isolation voltage TH and SMD
version optocouplers 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.
VDE STANDARDS
These couplers perform safety functions according to the
following equipment standards:
•DIN EN 60747-5-5 (VDE 0884-5)
Optocoupler for electrical safety requirements
