Procurement Notes

Verify the specific suffix or variant code against the manufacturer's current datasheet to ensure compatibility with required pinout and electrical specifications. Confirm RoHS compliance status and packaging type (tube vs. reel) directly with authorized distributors. Cross-reference the part number with official Everlight documentation to validate active status and avoid obsolete stock substitutions.

Selection Notes

Select this component when high-speed digital isolation is required alongside high voltage withstand capabilities. The base-connected transistor output allows for faster switching compared to standard phototransistors without base access. Ensure the application environment stays within the specified temperature limits and that the 1 Mbps bandwidth meets the system's data throughput requirements.

Part Context

This part belongs to Everlight's high-speed optocoupler family, designed for applications demanding rapid signal transfer across isolated barriers. It serves as a critical interface component in systems requiring galvanic isolation to protect sensitive electronics from noise and high voltages present in power stages or external interfaces.

Replacement Considerations

Consult official Everlight substitution guides for direct replacements. Compatible alternatives may include other high-speed transistor-output optocouplers with matching 8-DIP packages and similar isolation ratings, provided pinouts and electrical characteristics are verified.
