Overview
The EL816(S)(B)(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 high isolation voltage of 5000 Vrms and supports a wide operating temperature range from -55°C to +110°C. It is available in a compact surface-mount 4-SMD package with gull-wing leads. Key electrical parameters include a collector-emitter breakdown voltage of 80 V minimum, a maximum forward current of 60 mA, and a maximum on-state current of 50 mA.
Feature Summary
- High isolation voltage capability between input and output terminals
- Wide operating temperature range suitable for demanding environments
- Compact surface-mount package design for space-constrained applications
Applications
- Signal isolation in industrial control systems
- Switching power supply feedback loops
- Microcontroller input/output isolation
Procurement Notes
Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required packaging and compliance standards. Confirm that the component status is active for your project timeline. Check for RoHS compliance documentation if environmental regulations apply. Ensure the supplier provides original manufacturer packaging to guarantee authenticity and storage integrity.
Selection Notes
Select this component when high isolation voltage and wide temperature operation are required in a small form factor. Consider the current transfer ratio specifications for signal fidelity needs. Evaluate the surface-mount footprint against PCB layout constraints. Compare performance metrics with alternative optocouplers if specific timing or gain characteristics differ significantly.
Part Context
This part belongs to the EL816 series of phototransistor optocouplers from Everlight Electronics. The series offers various packaging options including DIP and SMD configurations. The EL816 family is widely used for general-purpose isolation tasks due to its reliability and cost-effectiveness. Variations in suffixes typically denote differences in packaging type, lead spacing, or compliance certifications rather than core functional changes.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements may not match the exact isolation voltage or package dimensions. Verify pinout compatibility before integration.
