EL816(S)(C)(TA)-V

Overview

The EL816(S)(C)(TA)-V is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector in a compact surface-mount package. The device provides high electrical isolation with a rated insulation voltage of 5000 Vrms and a creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of 80 V, a maximum forward current of 50 mA, and a typical rise/fall time of 4 µs/3 µs. It operates within a temperature range of -55°C to +110°C.

Feature Summary

• High isolation voltage capability between input and output circuits
• Compact small outline surface-mount package design
• Wide operating temperature range for industrial environments
• Compliant with international safety standards including UL and VDE

Applications

• Industrial control systems requiring signal isolation
• Consumer appliances with mains interface requirements
• Computer peripheral communication interfaces
• Power supply feedback loop isolation

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required lead spacing and packaging type. Confirm RoHS compliance status and safety certification markings (UL/VDE) are present on the component marking. Check for end-of-life or obsolescence notices from Everlight before finalizing procurement plans.

Selection Notes

Select this component when a surface-mount solution is required for galvanic isolation in low-speed digital signaling applications. Ensure the circuit design accommodates the specified CTR range and saturation voltage. Verify that the PCB footprint matches the 4-SMD outline dimensions provided in the mechanical drawings.

Part Context

This part belongs to the EL816 series of optocouplers, which are widely used for isolating signals between different voltage domains. The series offers both DIP and SMD packages, providing flexibility for various board layout constraints while maintaining consistent electrical performance characteristics across the product line.

Replacement Considerations

Direct substitutes may include other EL816 variants with compatible pinouts such as EL816(S)(X)(TA)-V or EL816(S)(D)(TA)-V. Verify that any replacement maintains the same isolation voltage rating and package dimensions to ensure mechanical fit.
