Overview
The EL816(S)(Y)(TA) is a single-element transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to a phototransistor detector within a compact surface-mount DIP-4 package. The device provides high isolation voltage of 5000 V rms and operates over a temperature range of -55 °C to +110 °C. Key electrical parameters include a minimum collector-emitter breakdown voltage of 80 V, a maximum forward current of 0.06 A, and a nominal current transfer ratio of 150% at IF=5mA, VCE=5V. It is RoHS compliant and UL approved.
Feature Summary
- High isolation voltage between input and output for enhanced safety
- Compact surface-mount packaging suitable for automated assembly
- Wide operating temperature range for diverse environmental conditions
Applications
- Signal isolation in industrial control systems
- Power supply feedback loops
- Microcontroller interface circuits
Procurement Notes
Verify the specific suffix (Y) corresponds to the required Current Transfer Ratio bin, as variations exist within the EL816 series. Confirm the package type matches the target PCB footprint. Ensure compliance with RoHS directives if applicable to the final product. Check for UL approval status if regulatory certification is required for the end application.
Selection Notes
Select this component when a single-channel transistor output optocoupler with high isolation voltage is needed. The Y suffix indicates a specific CTR bin; verify this meets circuit gain requirements. Consider the surface-mount form factor for space-constrained designs. Compare against other EL816 variants if different CTR ranges or leaded packages are preferred.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series typically includes various CTR bins and package options, such as DIP-4 and SMD configurations. The EL816 family is widely used for general-purpose signal isolation due to its reliability and standard pinout compatibility.
Replacement Considerations
Direct replacements may include other EL816 variants with matching CTR bins or compatible transistor output optocouplers from other manufacturers that share the same pinout and isolation ratings. Verify electrical parameters and package dimensions before substitution.
