Overview
The EL816(S1)(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an NPN phototransistor output and provides high isolation voltage of 5000 Vrms between input and output circuits. The device operates within a temperature range of -55°C to +110°C. Key electrical parameters include a collector-emitter breakdown voltage of 80V, maximum forward current of 60mA, and maximum on-state current of 50mA. The current transfer ratio ranges from 50% to 600% at IF=5mA and VCE=5V. The component is available in compact surface mount packages.
Feature Summary
- High isolation voltage capability for secure circuit separation
- Wide operating temperature range suitable for demanding environments
- Compact small outline package design for space-constrained applications
Applications
- DC input protection for electronic circuits
- Secure data transmission systems
- Signal isolation in industrial control equipment
Procurement Notes
Verify the specific suffix codes (S1, TB) against official Everlight documentation to confirm exact packaging type and compliance status. Ensure the part number matches the required isolation voltage and package style for your design. Cross-reference with authorized distributors to confirm availability and authenticity. Check for RoHS compliance markings as specified in the datasheet.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required. Consider the current transfer ratio range for signal integrity needs. Verify package compatibility with PCB layout constraints. Ensure the NPN phototransistor output aligns with the receiving circuit requirements.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight. The series is designed for general-purpose isolation applications. Variants differ primarily in packaging and compliance certifications. The EL816 family is widely used in industrial and consumer electronics for signal coupling and noise immunity.
Replacement Considerations
Check for direct substitutes like EL817 variants if pinout compatibility is critical. Verify that any replacement maintains the 5000 Vrms isolation rating and similar CTR specifications. Ensure the alternative part supports the same operating temperature range and package dimensions.
