Overview
The ELD207(TB)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an 8-SOP package with a 3.75kVrms isolation voltage. The device provides a high current transfer ratio of up to 200% at 10mA input current. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.2V, and a maximum DC forward current of 60mA. The saturation voltage is limited to 400mV, with switching times of 5µs (on) and 4µs (off).
Feature Summary
- Dual-channel configuration for simultaneous signal isolation.
- High isolation voltage rating of 3750Vrms.
- High current transfer ratio capability up to 200%.
- Low dark current specification for improved noise immunity.
Applications
- Industrial communication interface isolation
- Microcontroller input/output isolation
- Power supply feedback circuits
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to ensure correct binning or packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual-channel isolation is required within a compact surface-mount footprint. Ensure the application voltage does not exceed the 80V collector-emitter limit. Verify that the required current transfer ratio meets the circuit design specifications under operating temperature conditions ranging from -55°C to 110°C.
Part Context
This component belongs to the ELD20x series of phototransistor output optocouplers. It shares architectural similarities with the ELD207(TA)-V variant, differing primarily in manufacturing lot or specific performance binning as defined by the suffix. The series is designed for general-purpose digital signal isolation in space-constrained applications.
Replacement Considerations
The ELD207(TA)-V is a documented related part number within the same product family. Verify functional equivalence regarding pinout and electrical characteristics before substitution. No other direct substitute part numbers are confirmed in public documentation.
