ISOCOM CNY17F-4X Optocoupler, Transistor Output, 6-Pin DIP, 5.3kV

The ISOCOM CNY17F-4X is a 1-channel, 6-pin optically coupled isolator, designed to provide reliable signal isolation and transmission in demanding electronic circuits. It combines a high-efficiency infrared light-emitting diode with an NPN silicon phototransistor to create a robust and effective isolation barrier, suitable for interfacing systems with different potentials and impedances.

A key feature of this optocoupler is its base pin being left unconnected. This design significantly improves noise immunity, making it an excellent choice for use in high electromagnetic interference (EMI) environments, such as industrial motor drive controls. With a high isolation voltage of 5.3kV, it ensures safe and reliable separation between input and output circuits.

Key Specifications & Performance

The device offers a forward current (If) of up to 60mA and a minimum Current Transfer Ratio (CTR) of 160%, ensuring efficient signal transfer. It features a high collector-emitter voltage (V(br)ceo) of 70V and a total power dissipation of 200mW, providing a robust performance envelope for various applications. Its compact DIP (Dual In-line Package) style makes it easy to integrate onto standard printed circuit boards.

Typical Applications

This optocoupler is ideally suited for DC motor controllers, where it isolates control signals from power stages. It is also perfect for general signal transmission between circuits of different voltage levels in industrial automation, programmable logic controllers (PLCs), and communication interfaces. Its reliability and noise immunity make it a staple in power supplies, measurement equipment, and other signal processing systems where electrical isolation is critical for safety and signal integrity.
