CNY74-4 Description

Short technical summary and product information.

The Telefunken CNY74-4 is a multichannel optocoupler designed for high safety requirements, featuring a phototransistor optically coupled to a gallium arsenide infrared emitting diode. This component is housed in a PDIP package and designed for through-hole mounting.

 

Key electrical specifications include a maximum forward current of 60mA, a maximum collector current of 50mA, and a high isolation voltage of 5000Vrms. The device has a maximum forward voltage of 1.6V and a maximum collector emitter saturation voltage of 300mV. It also provides a current transfer ratio of 120% and a reverse breakdown voltage of 6V.

 

With a maximum power dissipation of 250mW and a DC voltage rating of 1.25V, the CNY74-4 is suitable for various applications. It operates within a temperature range of -55°C to 100°C, making it robust for different environmental conditions. The optocoupler has a rise time of 3µs and a fall time of 4.7µs.

 

This optocoupler is ideal for applications requiring electrical isolation between circuits, such as in power supply control, signal isolation in noisy environments, and interfacing between low-voltage logic and high-voltage systems.
