EL1012(TA)-VG

Overview

The EL1012(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides an insulation voltage of 5000 Vrms. The device is housed in a 4-pin SOP package with long creepage distance, designed for surface mount applications. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a forward current rating of 60 mA. The component supports a wide operating temperature range from -55 °C to +110 °C and has a power dissipation capacity of 250 mW.

Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Utilizes an NPN phototransistor output stage for signal transmission.
• Features a 4-pin SOP package with extended creepage distance for enhanced safety.

Applications

• General-purpose signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops requiring galvanic isolation

Procurement Notes

Verify the specific suffix TA-VG against the manufacturer's latest datasheet to confirm pinout and creepage specifications. Ensure compliance with RoHS directives as indicated in official documentation. Check for moisture sensitivity levels prior to soldering to prevent package damage during reflow processes.

Selection Notes

Select this component when a standard NPN output optocoupler with 5000 Vrms isolation is required. The long creepage SOP package makes it suitable for applications demanding higher safety clearance than standard packages. Verify that the 60 mA forward current and 80 V collector voltage meet the circuit requirements.

Part Context

This part belongs to the EL1012 series of transistor output optocouplers from Everlight. The TA-VG suffix typically denotes specific packaging and environmental compliance attributes, such as tape-and-reel delivery and halogen-free materials, distinguishing it from bulk or leaded variants within the same functional family.

Replacement Considerations

Direct replacements may include other 4-pin SOP NPN optocouplers with similar 5000 Vrms isolation ratings. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with Everlight's change notification documents for any updated equivalent part numbers.
