EL1012-G

Overview

The EL1012-G is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device utilizes a 4-pin long creepage SOP package. Key electrical parameters include a minimum current transfer ratio of 63% and a maximum of 125%, both measured at a forward current of 10 mA.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed with a long creepage distance for enhanced safety

Applications

• General purpose signal isolation
• Microprocessor system interfacing
• Solid-state relay drivers

Procurement Notes

Verify the specific suffix against official Everlight documentation to confirm packaging type, as variations exist between tube and reel formats. Ensure compliance with RoHS directives and moisture sensitivity levels required for your assembly process before ordering.

Selection Notes

Select this component when a standard NPN output configuration is required for digital signal isolation. Consider the 5000 Vrms isolation rating for applications demanding robust barrier protection. Verify that the SOP-4 footprint matches your PCB design constraints.

Part Context

This part belongs to the EL1012 family of optocouplers, which are designed for general-purpose isolation tasks. The series typically offers cost-effective solutions for separating low-voltage control circuits from higher-voltage loads or noisy environments.

Replacement Considerations

Check for EL1012(TA)-G if reel packaging is specifically required instead of tubes. Verify pinout compatibility with existing designs before substituting.
