EL1018(TA)-VG

Overview

The EL1018(TA)-VG is a single-channel optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to 110°C. The device provides 5000 Vrms isolation voltage and supports a maximum forward current of 60 mA with a forward voltage of 1.45 V typical. The collector-emitter output voltage reaches 80 V, while the power dissipation is rated at 250 mW. Transition times are specified as 2 µs rise and 3 µs fall, with maximum limits of 18 µs for both. It utilizes a 4-pin long creepage SOP package.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Utilizes an NPN phototransistor for signal transmission
• Designed for surface mount installation in compact layouts

Applications

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

Procurement Notes

Verify the specific suffix TA and VG against the manufacturer's latest datasheet to confirm pinout configuration and creepage distance requirements. Ensure the ordering information matches the exact package style intended for the PCB layout. Cross-reference the component marking with official Everlight documentation to authenticate the source and prevent counterfeit components from entering the supply chain.

Selection Notes

Select this component when a single channel with NPN output is required for galvanic isolation. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 60 mA forward current capability against the driving circuit constraints. Confirm that the SOP-4 package dimensions fit the available board space and thermal management strategy for the target environment.

Part Context

This part belongs to the EL1018 series of transistor output optocouplers from Everlight Electronics. The series is widely used for general-purpose isolation tasks. The specific variant includes packaging characteristics defined by the TA and VG suffixes, which relate to the physical housing and compliance standards. It serves as a standard solution for breaking ground loops and protecting low-voltage control circuits from high-voltage noise.

Replacement Considerations

Check for direct equivalents such as the EL1019(TA)-VG if PNP output is acceptable. Verify pin compatibility before substituting with other SOP-4 optocouplers. Ensure replacement parts meet the same 5000 Vrms isolation and 60 mA forward current specifications.
