EL1010-G

Overview

The EL1010-G is a single-channel transistor output optocoupler from Everlight Electronics. It integrates an infrared emitting diode optically coupled to an NPN phototransistor detector. The device utilizes a 4-pin SOP package with long creepage distance, designed for robust electrical isolation. Key specifications include a maximum isolation voltage of 5000 Vrms and a collector-emitter breakdown voltage (Vceo) of 80 V. The unit operates within a temperature range of -40°C to +100°C and complies with halogen-free and Sb2O3-free compound requirements.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits via optical coupling
• Features a compact 4-pin SOP package with extended creepage distance for enhanced safety
• Utilizes an NPN phototransistor detector for reliable signal transmission across different potentials

Applications

• Signal transmission between circuits of different potentials and impedances
• Programmable controllers and system appliances
• Telecommunication equipment interfaces
• Home appliances such as fan heaters

Procurement Notes

Verify the specific suffix designation against official Everlight documentation to confirm pin configuration and creepage specifications. Ensure compliance with RoHS and halogen-free material requirements relevant to the target application environment. Cross-reference the datasheet revision date to validate current parameter limits before integration into final designs.

Selection Notes

Select this component when high isolation voltage is required in a small form factor. The NPN output type suits digital switching applications. Consider the operating temperature range and forward current limits relative to the driving circuit capabilities. Ensure the SOP package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the EL101X-G series, which includes variants like EL1014, EL1019, and EL1012. All members share the same fundamental architecture of an IR LED coupled to a phototransistor in a 4-pin long creepage SOP package. The series is designed for general-purpose isolation tasks in industrial and consumer electronics.

Replacement Considerations

Direct substitutes within the same family include EL1014, EL1019, EL1012, EL1013, EL1017, and EL1018. Verify that the alternative variant meets the specific isolation voltage and package creepage requirements of the original design.
