ELD217(TA)-V

Overview

The ELD217(TA)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics. It features an 8-pin SOP package with a 3750 Vrms insulation voltage. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a forward current rating of 60 mA. The device exhibits a typical rise time of 1.6 µs and a maximum current transfer ratio of 100%.

Feature Summary

• Dual-channel configuration for independent signal isolation
• High insulation voltage capability for safety-critical applications
• SMD/SMT compatible surface mount packaging

Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission in noisy environments
• Power supply feedback loops

Procurement Notes

Verify the specific suffix (TA) against the manufacturer's latest datasheet to confirm pinout and material compliance. Ensure the ordering code matches the exact package variant required for your PCB footprint. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when dual-channel isolation is required within a compact SOP-8 footprint. Consider the 80 V collector-emitter voltage limit and 50 mA collector current capacity for load compatibility. Evaluate the 1.6 µs rise time against system speed requirements to ensure adequate signal integrity for the intended application frequency.

Part Context

This part belongs to Everlight's ELD217 series of phototransistor output optocouplers. The series is designed for general-purpose isolation tasks. The TA suffix typically denotes specific tape-and-reel packaging or material specifications. It serves as a compact solution for replacing relay-based isolation in modern electronic designs.

Replacement Considerations

Consult official substitution guides for equivalent dual-channel optocouplers with matching 3750 Vrms isolation ratings. Verify that alternative parts maintain compatible SOP-8 pinouts and similar electrical characteristics such as CTR and switching speeds.
