Overview
The EL817(S1)(C)(TB)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector, providing electrical isolation between input and output circuits. The device features a maximum isolation voltage of 5000 Vrms and supports surface mount installation in a compact package. Key electrical parameters include a collector-emitter breakdown voltage of 35 V minimum, a maximum forward current of 60 mA, and a typical current transfer ratio ranging from 200% to 400%. The unit operates within a temperature range of -55°C to +110°C.
Feature Summary
- High isolation voltage capability between input and output terminals
- Compact small outline surface mount package design
- Compliance with lead-free and RoHS environmental standards
Applications
- General purpose signal isolation in electronic circuits
- Switching applications requiring galvanic isolation
- Microprocessor interface circuits for noise immunity
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix designation matches project requirements, as variations may exist within the EL817 series. Check for end-of-life status or availability constraints prior to finalizing procurement plans. Ensure compliance with relevant safety certifications such as UL and VDE for intended application environments.
Selection Notes
Select this component when high isolation voltage and surface mount compatibility are required. Consider the current transfer ratio specifications for logic level interfacing needs. Evaluate thermal management requirements given the operating temperature range. Compare against alternative packages if space constraints differ from the standard small outline form factor.
Part Context
This part belongs to the EL817 series of optocouplers, which are widely used for isolating low-voltage control signals from higher-voltage power circuits. The series typically offers various packaging options including DIP and SMD configurations. The EL817 family is known for its reliability in industrial and consumer electronics applications requiring robust signal transmission across isolated boundaries.
Replacement Considerations
