Transistor, Photovoltaic Output Optoisolators Procurement Notes

This component is officially listed as obsolete and no longer in production by onsemi. Sourcing new original units from authorized distributors is not possible. Buyers must verify the authenticity and condition of any available surplus stock carefully, as availability is limited to existing inventory held by third-party suppliers.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Engineers should prioritize alternative active components due to the obsolete status of this part. When selecting replacements, ensure compatibility with the required 5300Vrms isolation rating and 100mA output current capability. Verify that the substitute device matches the 6-DIP package dimensions and maintains similar switching speed characteristics for direct board integration.

Transistor, Photovoltaic Output Optoisolators Part Context

The CNX82A300W belongs to the broader family of transistor output optocouplers manufactured by onsemi (formerly Fairchild Semiconductor). These devices are designed for applications requiring reliable electrical isolation between low-voltage control logic and higher-voltage power stages. The specific model was widely used in legacy designs before being phased out in favor of newer generation components.
