Overview
The EL815(S)(TA)-V is a single-channel photodarlington output optocoupler manufactured by Everlight Electronics. It features a high current transfer ratio with a minimum of 600% at an input forward current of 1 mA and collector-emitter voltage of 2 V. The device provides robust electrical isolation with a rated insulation voltage of 5000 Vrms. It operates within a temperature range of -55°C to +110°C and dissipates up to 200 mW of power. Key electrical limits include a maximum collector-emitter voltage of 35 V, a maximum collector current of 80 mA, and a reverse voltage rating of 6 V for the output transistor.
Feature Summary
- High current transfer ratio ensuring efficient signal transmission from input to output
- Strong electrical isolation capability between input and output circuits
- Wide operating temperature range suitable for demanding industrial environments
Applications
- Telephone sets and telephone exchangers
- Sequence controllers
- System appliances and measuring instruments
- Signal transmission between circuits of different potentials and impedances
Procurement Notes
Verify component authenticity through official Everlight channels or authorized distributors. Confirm that the specific suffix (S)(TA)-V matches the required surface mount tape and reel configuration. Check for end-of-life status as some sources indicate potential discontinuation. Ensure compliance with relevant safety approvals such as UL, VDE, and CSA for the intended application region.
Selection Notes
Select this component when high gain is required due to its photodarlington output structure. The SMD tape and reel format facilitates automated assembly processes. Consider the slow rise and fall times inherent to darlington outputs when designing for high-speed digital signals. Verify that the 35 V collector-emitter voltage rating meets the load requirements of the target circuit.
Part Context
This part belongs to the EL815 family of phototransistor optocouplers. Variants exist in DIP packages and surface mount configurations. The TA suffix specifically denotes a tape and reel packaging type for surface mounting. Other variants may offer different lead spacing or package styles while maintaining similar electrical characteristics.
Replacement Considerations
Consult official datasheets for direct pin-compatible substitutes within the same isolation voltage class. Generic replacements must match the photodarlington output type and minimum 600% CTR specification. Verify that alternative components hold equivalent safety certifications if used in regulated applications.
