EL1019(TA)-G

Overview

The EL1019(TA)-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It integrates an infrared emitting diode with an NPN phototransistor detector within a compact four-pin SOP package featuring long creepage distance. The device provides electrical isolation of 5000 Vrms between input and output circuits. Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 80V, a collector-emitter saturation voltage (VCEsat) of 300mV, and a high current transfer ratio capability suitable for signal transmission applications.

Feature Summary

• Provides robust electrical isolation via an infrared LED coupled to an NPN phototransistor detector
• Features a four-pin SOP package designed with long creepage distance for enhanced safety
• Supports signal transmission between circuits operating at different potentials and impedances

Applications

• Programmable logic controllers
• System appliances and measuring instruments
• Telecommunication equipment
• Home appliances such as fan heaters

Procurement Notes

Verify the specific suffix designation when ordering, as variations exist within the EL101X-G series. Confirm that the required package type matches the long creepage SOP configuration documented in the official datasheet. Ensure compliance with halogen-free and RoHS requirements if specified for the project. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before procurement.

Selection Notes

Select this component for applications requiring galvanic isolation between low-voltage control circuits and higher-voltage loads. The 80V collector-emitter breakdown voltage allows for driving moderate load currents. Consider the package's long creepage distance when designing PCB layouts for high-voltage isolation standards. Verify that the input forward current and output current transfer ratio meet the specific interface requirements of the target system.

Part Context

This device belongs to the EL101X-G series from Everlight Electronics, which includes variants like EL1014, EL1010, and EL1012. All members of this family share the same fundamental architecture of an infrared emitter coupled to a phototransistor in a 4-pin long creepage SOP package. The series is designed for general-purpose signal isolation in industrial and consumer electronic applications.

Replacement Considerations

Direct replacements within the same family include EL1014, EL1010, EL1012, EL1013, EL1017, and EL1018. These parts share identical pin configurations and package styles. Verify specific electrical parameters such as current transfer ratio and switching speed against the original design requirements before substituting.
