FOD816300W is listed in the Logic Output Optoisolators range at ChipApex. The manufacturer field lists onsemi. Its product description is OPTOISOLTR 5KV DARLINGTON 4-DIP. Review the specifications below when checking this part for your BOM.
The FOD816300W is a discontinued optoisolter featuring a Darlington transistor output and a single channel. It provides 5000Vrms isolation voltage with a CMTI of unspecified high immunity. The device supports AC/DC input types and delivers an output current of 80 mA per channel. Typical rise and fall times are 60µs and 53µs respectively, with a maximum DC forward current of 50mA. It operates within a temperature range of -30°C to 100°C and is housed in a 4-DIP package.
This component is officially marked as obsolete and no longer manufactured by onsemi. Procurement must rely on third-party distributors or surplus stock providers. Verify the authenticity of available units through authorized channels. Ensure that any sourced inventory matches the original datasheet specifications to maintain system reliability. Check for potential counterfeit risks when purchasing from non-primary sources.
Designers should consider alternative components due to the end-of-life status. Evaluate replacement options based on pin compatibility and electrical parameters. Verify that substitute devices meet the required isolation voltage and output current specifications. Review lead times and availability constraints associated with legacy parts. Confirm thermal performance requirements align with the operating temperature range of potential replacements.
The FOD816300W belongs to the FOD816 series of optocouplers produced by onsemi. This series typically includes various packages and output configurations such as transistors and logic gates. The specific model utilizes a DIP package suitable for through-hole mounting. It represents a standard solution for general-purpose isolation applications prior to its discontinuation.
LTV-8141 is listed as a direct substitute part number.
