VISHAY CNY17-4 6-Pin DIP Optocoupler, 60mA, 5kV, 160%

The VISHAY CNY17-4 is a high-performance, 1-channel phototransistor output optocoupler in a 6-pin DIP (Dual In-line Package). Designed to ensure reliable signal transmission, this device consists of a gallium arsenide infrared emitting diode that is optically coupled to a silicon NPN phototransistor. This configuration allows for the transmission of signal information, including DC levels, while maintaining a high degree of electrical isolation between the input and output circuits.

A key feature is its minimum Current Transfer Ratio (CTR) of 160%, which indicates excellent efficiency in transferring the input signal to the output. It is rated for a forward current (If) of up to 60mA and boasts a high isolation test voltage of 5000Vrms (5kV), ensuring long-term stability and safety in demanding electrical environments. This robust isolation makes it a dependable component for protecting sensitive circuitry from voltage spikes and noise.

Versatile Applications

This optocoupler is an ideal, solid-state replacement for electromechanical relays and transformers in a wide range of applications. Its use extends from digital interface circuits, where it provides noise-free switching, to analog applications such as CRT (Cathode Ray Tube) display modulation. Its reliability and high isolation voltage make it particularly suited for systems requiring secure signal separation.

Ideal For:

• Communications and networking equipment, where signal integrity and isolation are critical.
• Industrial control systems requiring robust interfacing between different voltage domains.
• Power supply feedback circuits and inverter controls.
• Any application demanding long-term stability and protection against high-voltage transients.

The compact DIP package is easy to handle and install on printed circuit boards (PCBs), making it a staple component for both prototyping and volume production.
