CNX83A300W

Transistor, Photovoltaic Output Optoisolators Overview

The CNX83A300W is a transistor output optocoupler manufactured by onsemi, designed for signal isolation in electronic circuits. It features a single channel configuration housed in a 6-DIP package with a pin pitch of 10.16mm (0.400 inches). The device provides an isolation voltage of 5300 Vrms between the input LED and output phototransistor. Key electrical parameters include a maximum collector-emitter voltage of 50V, a typical forward voltage of 1.2V, and a collector saturation voltage of approximately 0.4V at specified currents. The unit operates within a temperature range of -55°C to +125°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'A300W' against the official onsemi datasheet to confirm package dimensions and lead finish specifications. Ensure compatibility with existing PCB footprints for the 6-DIP form factor. Check for end-of-life status or alternative recommendations from the manufacturer before finalizing procurement plans.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard transistor output optocoupler with a 6-pin DIP footprint is required. Consider the 5300 Vrms isolation rating for safety compliance in mains-connected equipment. Evaluate the current transfer ratio and switching speed requirements against the application's timing constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to onsemi's portfolio of discrete optoelectronic components. It serves as a general-purpose isolation device within the broader category of optocouplers. The 6-DIP packaging distinguishes it from smaller surface-mount alternatives while maintaining compatibility with legacy through-hole designs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Consult the onsemi datasheet for direct pin-compatible replacements. Verify that any substitute maintains the same 6-DIP package outline and meets or exceeds the 5300 Vrms isolation voltage requirement for safety-critical applications.
