The CNX35U300W is a photovoltaic output optoisolator manufactured by onsemi. It features a typical forward voltage of 1.15V and a maximum DC forward current of 100 mA. The device exhibits a maximum Vce saturation of 400mV and operates within a temperature range of -40°C to 100°C. This component provides electrical isolation with a specified isolation voltage rating.
Verify the specific datasheet revision and ordering suffixes when sourcing, as package dimensions or marking codes may vary between manufacturing lots. Confirm that the supplier provides traceable documentation matching the CNX35U300W part number to ensure compliance with technical specifications and quality standards.
Select this component when high-voltage isolation is required without active switching elements in the output stage. The photovoltaic nature makes it suitable for applications needing zero quiescent current in the off state. Ensure the input current limits and isolation voltage ratings align with the system's safety requirements.
This device belongs to onsemi's portfolio of optoelectronic components designed for reliable signal transmission across isolated barriers. It utilizes LED-to-photovoltaic cell technology, distinguishing it from transistor-output optocouplers by its unique drive characteristics and lack of base terminal connection in standard configurations.
Consult official substitution guides for equivalent photovoltaic output isolators. Verify pinout compatibility and isolation voltage ratings before replacing with alternative manufacturers' parts to ensure circuit integrity.
