FOD852300W

Overview

The FOD852300W is a single-channel photodarlington output optocoupler manufactured by onsemi. It features a 4-pin DIP package with 0.4-inch lead spacing, designed for through-hole mounting. The device provides 5000 Vrms isolation voltage and supports a maximum collector-emitter voltage of 300 V. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.4 V, and a collector current of 150 mA. The current transfer ratio ranges from 1000% to 15000%, with rise and fall times of 300 µs and 100 µs respectively. Operating temperature spans -30°C to +100°C.

Feature Summary

• High current transfer ratio capability for efficient signal transmission
• Robust 5000 Vrms insulation voltage for safety isolation
• Photodarlington output structure for high gain
• Wide operating temperature range for industrial environments

Applications

• Industrial process control systems
• Power supply feedback loops
• Solid-state relay drivers
• Microcontroller input isolation

Procurement Notes

Verify the specific suffix '300W' corresponds to the 4-DIP (0.400 inch) package configuration as documented in official datasheets. Confirm RoHS compliance status and check for any recent lifecycle changes or obsolescence notices directly from onsemi before finalizing procurement plans.

Selection Notes

Select this component when high current transfer ratios are required for driving loads directly. Ensure the 300 V collector-emitter voltage rating exceeds the circuit's peak voltage requirements. Verify that the slow switching speeds are acceptable for the application frequency, as faster alternatives exist within the family.

Part Context

This part belongs to the FOD852 series of photodarlington optocouplers. It shares functional similarities with other members like the FOD8523SD but differs in packaging and specific electrical tolerances. The series is designed for general-purpose isolation tasks requiring high sensitivity.

Replacement Considerations

Direct substitutes may include other FOD852 series variants with compatible pinouts. Verify package dimensions and electrical characteristics match before substitution.
