EL816(S)(D)(TD)-V

Overview

The EL816(S)(D)(TD)-V is a single-element transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with a phototransistor detector in a compact surface-mount DIP-4 package. The device provides high isolation voltage of 5000 V rms between input and output, with a creepage distance exceeding 7.62 mm. Key electrical parameters include a collector-emitter breakdown voltage of at least 80 V, a maximum forward current of 60 mA, and a nominal current transfer ratio ranging from 50% to 600%. It operates within a temperature range of -55 °C to +110 °C and complies with RoHS standards.

Feature Summary

• High isolation voltage capability between input and output circuits
• Compact surface-mount packaging design for space-constrained applications
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial control systems requiring signal isolation
• Communication equipment interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure correct pinout and performance characteristics. Confirm compliance requirements such as RoHS status and relevant safety approvals like UL or VDE before procurement. Ensure the selected variant matches the required isolation voltage and current transfer ratio specifications for the intended circuit design.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factor are required. Consider the current transfer ratio range and operating temperature limits during circuit design. Verify that the package type meets the PCB layout constraints and that the isolation rating satisfies the safety standards applicable to the final application environment.
