Overview
The EL815(S)(TU) is a single-channel phototransistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features a Photodarlington output configuration housed in a 4-SMD surface mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a minimum current transfer ratio (CTR) of 600% at IF=1mA and VCE=2V, a maximum collector-emitter voltage of 35V, and a maximum forward current of 60 mA. The component operates within a temperature range of -55°C to +110°C.
Feature Summary
- High current transfer ratio for efficient signal transmission
- High isolation voltage ensuring circuit safety
- Surface mount packaging for automated assembly
Applications
- Telephone sets
- Telephone exchanges
- Industrial control systems
Procurement Notes
Verify the specific suffix TU indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation as manufacturing practices may change. Check availability as this component type may be subject to end-of-life notices or discontinuation by the manufacturer. Ensure the supplier provides valid traceability documents for quality assurance purposes.
Selection Notes
Select this component when high gain is required due to the Darlington output structure. The surface mount form factor suits space-constrained designs requiring automated placement. Verify that the 35V output voltage rating meets the load requirements. Consider the slow switching speed inherent to photodarlington outputs if high-frequency operation is needed.
Part Context
This part belongs to the EL815 family of transistor output optocouplers from Everlight. Variants exist in DIP and other SMD packages with different lead spacings. The family is designed for general-purpose isolation applications where high CTR is beneficial. Always consult the specific datasheet for the exact suffix to confirm mechanical dimensions and electrical tolerances.
Replacement Considerations
Direct substitutes include EL815(S)(TB) which shares similar electrical characteristics but may differ in packaging format. Other equivalents in the EL815 series should be verified against pinout and isolation voltage requirements before substitution.
