EL1112(TA)-VG

Overview

The EL1112(TA)-VG is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a base terminal for enhanced switching speed and stability. The device provides high isolation capability with a rated insulation voltage of 5000 Vrms. It is housed in a compact SOP-5 surface-mount package, suitable for space-constrained designs. The component is RoHS compliant and halogen-free, meeting environmental standards for modern electronics manufacturing.

Feature Summary

• Integrated base terminal on the NPN phototransistor to improve switching performance
• High dielectric isolation strength between input and output circuits
• Surface-mount SOP-5 package design for automated assembly

Applications

• Signal isolation in industrial control systems
• Interface circuits for microcontrollers and logic devices
• Power supply feedback loops requiring galvanic separation

Procurement Notes

Verify the specific suffix TA against the latest Everlight datasheet to confirm pinout and packaging details. Ensure compliance with RoHS and halogen-free requirements if mandated by project specifications. Check moisture sensitivity levels for proper storage and reflow soldering profiles. Confirm availability status as distribution channels may report limited stock or discontinuation notices.

Selection Notes

Select this component when a fast-switching transistor output is required alongside high-voltage isolation. The presence of a base terminal allows for external biasing to optimize response time compared to standard phototransistors. Consider the SOP-5 footprint compatibility during PCB layout. Evaluate the 5000 Vrms isolation rating against system safety standards.

Part Context

This part belongs to the EL111x series of transistor output optocouplers from Everlight. It shares functional similarities with models like EL1113 and EL1114 but differs in specific electrical characteristics and pin configurations. The TA suffix typically denotes tape and reel packaging for high-volume production environments.

Replacement Considerations

Direct substitutes include EL1113(TA)-VG and EL1114(TA)-VG from the same manufacturer family. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Cross-reference with other SOP-5 transistor optocouplers if Everlight parts are unavailable.
