EL206(TA)

Overview

The EL206(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor with a base terminal for improved switching performance. The device provides high isolation voltage of 3750 Vrms between input and output circuits. It is housed in an 8-SOP surface-mount package, suitable for automated assembly processes. Key electrical parameters include a minimum current transfer ratio of 63% at 10 mA forward current and a collector-emitter breakdown voltage of 80 V. The component operates within a temperature range of -55°C to 110°C.

Feature Summary

• Integrated base terminal on the phototransistor output to enhance switching speed and reduce storage time.
• High insulation voltage capability ensuring reliable signal isolation between input and output circuits.
• Surface-mount 8-SOP package design compatible with standard automatic placement equipment.

Applications

• Signal isolation in industrial control systems
• Interface circuits for microprocessors and logic devices
• Power supply feedback loops

Procurement Notes

Verify the specific suffix TA indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation as requirements vary by region. Check lead times due to potential supply chain fluctuations for SMD components. Ensure moisture sensitivity handling protocols are followed during storage and assembly.

Selection Notes

Choose this component when fast switching speeds are required compared to standard phototransistor optocouplers. The base pin allows for external biasing or faster discharge of stored charge. Verify that the 3750 Vrms isolation rating meets system safety standards. Ensure the SOP-8 footprint matches the PCB layout constraints.

Part Context

This part belongs to the EL206 series of transistor output optocouplers from Everlight. The TA suffix specifically denotes the tape and reel packaging format, distinguishing it from bulk or cut-tape variants. It shares the same internal die and electrical characteristics as other EL206 variants but differs in shipping configuration.

Replacement Considerations

Direct substitutes may include other 8-pin SOP transistor optocouplers with similar CTR and isolation ratings. Verify pinout compatibility and electrical specifications before substitution. Consider equivalents from other manufacturers offering comparable switching speeds and isolation voltages.
