EL1019(TA)-VG

Overview

The EL1019(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides 5000 Vrms insulation voltage for circuit isolation. The device operates within a temperature range of -55°C to 110°C and has a maximum collector-emitter voltage of 80V. It supports a continuous forward current of 60mA and offers a typical propagation delay of 3µs. The component is housed in a compact SOP-4 package with a 2.54mm pin pitch, designed for surface mount applications requiring reliable signal transmission across isolated boundaries.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
• Features an NPN phototransistor output stage suitable for digital signal interfacing.
• Designed with a long creepage distance in the SOP-4 package to enhance safety compliance.

Applications

• Industrial control systems requiring signal isolation
• Communication equipment interface circuits
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix TA-VG against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels if storage conditions have been exceeded. Cross-reference the pinout configuration with the target PCB footprint to prevent installation errors during assembly.

Selection Notes

Select this component when a single-channel isolation barrier with an NPN output is required. Consider the 5000 Vrms rating for safety standards compliance. Evaluate the 3µs switching speed against system timing requirements. Confirm that the SOP-4 form factor fits the available board space constraints.

Part Context

This part belongs to the EL101x series of transistor output optocouplers from Everlight. These devices are engineered for general-purpose isolation tasks where moderate speed and high voltage withstand capability are necessary. The series utilizes standard LED-to-phototransistor architecture for cost-effective signal transfer.

Replacement Considerations
