CNW84S

Transistor, Photovoltaic Output Optoisolators Overview

The CNW84S is a single-channel optocoupler manufactured by onsemi, featuring an infrared emitting diode optically coupled to an NPN phototransistor. It provides a high isolation voltage of 5900Vrms and utilizes a wide-body SMD package with a 10.16 mm pin distance. The device offers a minimum current transfer ratio of 0.63% at 10mA input current and a maximum collector-emitter saturation voltage of 400mV. Designed for reliable data transmission, it lacks a connected base pin to enhance noise immunity.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High isolation voltage rating of 5900Vrms for safe signal transmission
• Wide-body encapsulation ensuring a minimum creepage distance of 10 mm
• Optimized for noise immunity through unconnected phototransistor base pin
