EL816(S)(A)(TA)

Overview

The EL816(S)(A)(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode optically coupled to an NPN phototransistor detector in a compact surface-mount package. The device provides high isolation voltage of 5000 V rms between input and output with a creepage distance exceeding 7.62 mm. It operates within a temperature range of -55°C to +110°C and supports a maximum forward current of 50 mA. The unit is RoHS compliant and UL recognized.

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

Applications

• Programmable controllers
• System appliances and measuring instruments
• Telecommunication equipments
• Signal transmission between circuits of different potentials

Procurement Notes

Verify the specific suffix configuration against official Everlight documentation to ensure correct pinout and electrical characteristics. Confirm compliance certifications such as UL or VDE approval are required for your target market. Check lead times and availability through authorized distributors, as surface-mount variants may have different supply chain dynamics compared to standard DIP packages.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factor are required. Ensure the CTR range meets circuit requirements at the intended operating current. Verify thermal management capabilities given the wide operating temperature range. Compare against alternative SMD optocouplers if space constraints or specific isolation ratings differ from standard EL816 specifications.

Part Context

This part belongs to the EL816 series of transistor output optocouplers. The series includes various packaging options including DIP and SMD configurations. The (S) indicates surface mount, while (TA) typically denotes tape and reel packaging. The series is widely used in industrial and consumer applications requiring galvanic isolation.

Replacement Considerations

Direct replacements include other EL816 series variants with compatible pinouts and electrical parameters. Verify that substitute parts maintain the same isolation voltage and CTR specifications. Consider equivalent parts from other manufacturers only if they meet all critical electrical and mechanical requirements.
