VISHAY CNY17-2 Optocoupler, 1 Channel, 60 mA, 5 kV, DIP-6

The VISHAY CNY17-2 is a high-performance, 1-channel optocoupler featuring a phototransistor output with a base connection, encapsulated in a standard DIP-6 package. It is designed to provide a high degree of electrical isolation between input and output circuits, capable of isolating signals up to 5 kV. This makes it an essential component for enhancing safety and preventing ground loops in sensitive electronic systems.

This device consists of an infrared gallium arsenide emitting diode optically coupled to a silicon NPN phototransistor, ensuring reliable signal transmission. It offers a minimum Current Transfer Ratio (CTR) of 63%, providing efficient coupling for both digital and analogue applications. The unit is ideal for replacing electromechanical relays and transformers in many interface scenarios, offering superior long-term stability, reduced size, and increased reliability.
