EL1119(TA)-VG

Overview

The EL1119(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor with a base terminal for enhanced switching performance and stability. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. It is housed in a 5-SOP surface-mount package, designed for compact circuit board layouts. The component operates as a DC input isolator, suitable for applications requiring reliable signal transmission across isolated barriers.

Feature Summary

• Integrated base terminal on the phototransistor output to improve switching speed and reduce storage time
• High isolation voltage rating ensuring robust protection between input and output circuits
• Surface-mount 5-SOP package design facilitating automated assembly and space-efficient integration

Applications

• Digital isolation for sensitive electronic circuits
• Signal transmission in microprocessor systems
• Interface circuits between logic families with different voltage levels

Procurement Notes

Verify the specific suffix TA-VG against the manufacturer's latest datasheet to confirm pinout compatibility and moisture sensitivity level requirements. Ensure that the 5-SOP footprint matches the PCB design guidelines provided in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when base-driven phototransistor performance is required for faster switching compared to standard versions. Confirm that the 5000 Vrms isolation rating meets the safety standards of the target application environment. Evaluate the 5-SOP package dimensions against available board space constraints during the initial design phase.

Part Context

This part belongs to the EL1119 series of transistor output optocouplers from Everlight. The series is characterized by high current transfer ratio capabilities and compact packaging. The EL1119(TA)-VG variant specifically denotes the tape-and-reel packaging configuration within the SOP-5 form factor family.

Replacement Considerations

Direct substitutes must match the 5-SOP package, NPN phototransistor with base output type, and minimum 5000 Vrms isolation voltage. Verify pin-to-pin compatibility and equivalent current transfer ratios before substitution.
