- Photodarlington output structure for high gain sensitivity
- Compact surface-mount design suitable for automated assembly
Applications
- Telephone sets
- Telephone exchangers
Procurement Notes
Verify the specific suffix variant against the official Everlight datasheet to confirm pinout and packaging dimensions. Confirm RoHS compliance status through the manufacturer's latest documentation. Ensure the selected component matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when high gain and fast switching are not critical but high isolation voltage is required. The Photodarlington output offers higher sensitivity compared to standard phototransistors. Verify that the SMD package type aligns with the PCB layout constraints and manufacturing capabilities.
Part Context
This part belongs to the EL815 series of optocouplers, which are designed for general-purpose isolation applications. The series includes various package options such as DIP and SMD configurations. The EL815(S1)(TB)-V specifically denotes the surface-mount variant with wide-lead spacing options available in related models within the same product family.
Replacement Considerations
Direct substitutes may include other 5000 Vrms Photodarlington optocouplers in 4-pin SMD packages. Verify compatibility regarding current transfer ratio, saturation voltage, and physical footprint before substitution.
