Overview
The onsemi FOD815300 is a single-channel optoisolator featuring a Darlington transistor output, housed in a 4-pin DIP package. It provides 5000Vrms isolation voltage and supports DC input with AC/DC compatibility. The device exhibits a minimum current transfer ratio of 600% at 1mA input current and a maximum of 7500%. Typical rise and fall times are specified for switching applications. Operating temperature ranges extend from -55°C to 110°C, ensuring reliability across industrial environments.
Feature Summary
- High current transfer ratio capability for efficient signal transmission
- Robust 5000Vrms electrical isolation between input and output circuits
- Darlington transistor output structure for high gain
- Wide operating temperature range suitable for harsh conditions
Applications
- Industrial automation control systems
- Power supply feedback loops
- Solid-state relay drivers
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix '300' indicates tube packaging configuration as per manufacturer documentation. Confirm RoHS compliance status for environmental regulations. Ensure the 4-DIP package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when high current gain is required due to the Darlington output stage. Consider the wide CTR range (600%-7500%) for design margin. Verify that the 5000Vrms isolation rating meets safety standards for the intended application voltage levels compared to lower-rated alternatives.
Part Context
Part of the FOD series from onsemi, designed for general-purpose isolation. The FOD815 variant specifically utilizes a Darlington output, distinguishing it from standard phototransistor outputs found in other models within the same family line.
Replacement Considerations
Direct substitutes include LTV-8141 from Lite-On. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage against original specifications before substitution.
