Overview
The EL817(S)(D)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a surface-mount package. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 35 V minimum, a maximum forward current of 50 mA, and a maximum forward voltage of 1.4 V. The nominal current transfer ratio is specified at 300%, with a maximum dark current of 100 nA. It operates within a temperature range of -55 °C to +110 °C.
Feature Summary
- High isolation voltage capability between input and output for safety compliance
- Compact surface-mount small outline package design
- RoHS compliant and lead-free construction
- Recognized by UL, VDE, SEMKO, NEMKO, DEMKO, FIMKO, CSA, and CQC
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground planes
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required isolation standards and packaging type. Confirm RoHS compliance status and approval numbers (UL, VDE) match project specifications. Check for obsolescence or lifecycle status before finalizing procurement plans.
Selection Notes
Select this component when a surface-mount solution is required for the EL817 series functionality. Ensure the 300% nominal CTR meets the circuit drive requirements. Verify that the 5000 Vrms isolation rating satisfies the safety clearance and creepage distance requirements of the target application environment.
Part Context
This part belongs to the EL817 series of optocouplers from Everlight Electronics. The series typically offers various pin configurations and isolation ratings. The EL817(S)(D)(TB)-V specifically denotes a surface-mount variant with defined thermal and mechanical characteristics suitable for automated assembly processes.
Replacement Considerations
Direct substitutes may include other EL817 surface-mount variants from Everlight or equivalent transistor-output optocouplers from manufacturers like Vishay or Sharp, provided pinout and isolation ratings match.
