EL1116(TA)-G

Overview

The EL1116(TA)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features a phototransistor output with an accessible base terminal, housed in a 5-SOP package designed for long creepage distance. The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to 110°C. Key electrical parameters include a collector-emitter voltage of 80V, collector current of 50mA, and typical switching times of 4µs (on) and 3µs (off).

Feature Summary

• Integrated base terminal on the phototransistor output allows for external control of sensitivity and switching speed.
• High insulation capability with 5000 Vrms isolation voltage between input and output circuits.
• Extended thermal operating range supports reliable performance in harsh industrial environments.

Applications

• Industrial automation signal isolation
• Microcontroller interface circuits requiring adjustable gain
• Power supply feedback loops

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolete status as some sources indicate discontinuation. Ensure packaging type matches design requirements. Validate datasheet version against production batch specifications.

Selection Notes

Choose this component when base-controlled phototransistor functionality is required for precise timing or sensitivity adjustment. Consider the 5-SOP package constraints for PCB layout. Evaluate thermal management needs given the wide operating temperature range. Compare isolation voltage requirements against system safety standards.

Part Context

This part belongs to Everlight's line of transistor output optocouplers. It shares functional similarities with other models like EL1116-VG but differs in packaging and specific parameter tolerances. The TA suffix typically denotes tape and reel packaging configuration.

Replacement Considerations

EL1116(TA)-VG may serve as a compatible alternative with similar electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Cross-reference datasheets for minor parameter differences.
