Overview
The EL816(S)(D)(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It integrates an infrared emitting diode with a phototransistor detector in a compact 4-SMD surface-mount package. The device provides high electrical isolation of 5000Vrms between input and output circuits, with a minimum creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of 80 V, a maximum forward current of 60 mA, and a typical forward voltage of 1.2 V. The unit supports a wide operating temperature range from -55°C to +110°C.
Feature Summary
- High isolation voltage capability between input and output terminals
- Compact surface-mount design for space-constrained applications
- Wide operating temperature range suitable for industrial environments
Applications
- Digital logic signal transmission and conversion
- Power supply control and switching circuits
- Electrical insulation isolation between circuits and systems
- Impedance transformation in electronic interfaces
Procurement Notes
Verify the specific suffix configuration against official Everlight documentation to ensure correct pinout and packaging type. Confirm RoHS compliance status and lead-free certification requirements prior to ordering. Cross-reference datasheet revisions to validate parameter consistency. Ensure procurement channels provide authentic components with traceable manufacturing records.
Selection Notes
Select this component when high-voltage isolation is required in a small form factor. The SMD package facilitates automated assembly processes. Consider the 80 V output voltage rating and 50 mA output current capability for load matching. Evaluate thermal management needs given the extended temperature range specifications.
Part Context
This part belongs to the EL816 series of optocouplers, which are widely used for galvanic isolation. The series typically offers both DIP and SMD packages. The EL816(S)(D)(TB) variant specifically denotes the surface-mount version with defined lead spacing and termination style, distinguishing it from through-hole alternatives within the same functional family.
Replacement Considerations
Direct replacements must match the 4-SMD footprint and 5000Vrms isolation rating. Verify that substitute parts maintain compatible CTR ranges and output transistor characteristics. Check for identical pin configurations to ensure board compatibility without redesign.
