EL1018-VG

Overview

The EL1018-VG is a single-channel phototransistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor collector-emitter configuration with a maximum collector-emitter voltage of 80 V and a continuous forward current rating of 60 mA. The device provides high isolation capability with a rated isolation voltage of 5000 Vrms. Key timing parameters include a rise time of 2 µs and a fall time of 3 µs at specified test conditions. The component is housed in a compact 4-pin SOP package designed for surface mount technology, offering a profile height of 2.0 mm.

Feature Summary

• High isolation voltage rating between input and output circuits
• Compact 4-pin SOP package with long creepage distance design
• Halogen-free compliant construction
• NPN phototransistor output configuration

Applications

• Industrial automation control systems
• Signal isolation in microprocessor interfaces
• Power supply feedback loops

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to ensure compliance with halogen-free requirements and pinout compatibility. Confirm that the procurement source provides original manufacturer datasheets to validate electrical characteristics such as current transfer ratio and isolation voltage ratings prior to integration into final designs.

Selection Notes

Select this component when high isolation voltage is required in a compact surface-mount footprint. Ensure the application circuit accounts for the phototransistor's saturation voltage and current transfer ratio variations across temperature ranges. Verify that the load resistance and supply voltage are within the 80 V collector-emitter limit and that the drive current does not exceed the 60 mA forward current specification.

Part Context

This part belongs to the EL1018 series of general-purpose phototransistor optocouplers from Everlight Electronics. The series is widely utilized for signal transmission between isolated circuits. The VG suffix typically denotes specific packaging or environmental compliance attributes, distinguishing it from standard tape-and-reel or bulk variants within the same functional family.

Replacement Considerations

Cross-reference with other EL1018 variants from Everlight or equivalent transistor-output optocouplers from other manufacturers. Verify pinout compatibility and ensure replacement parts meet the same 5000 Vrms isolation and 80 V collector-emitter voltage requirements.
