EL205(TA)

Overview

The EL205(TA) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides an insulation voltage of 3750 Vrms. The device is housed in an 8-SOP package and is supplied in reel packaging. It is designed for applications requiring electrical isolation between input and output circuits.

Feature Summary

• Provides galvanic isolation via infrared LED and NPN phototransistor pair
• Offers high insulation voltage capability for safety-critical circuits
• Designed for surface-mount assembly in compact electronic systems

Applications

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

Procurement Notes

Verify the specific suffix (TA) against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compliance with RoHS directives if required by your application standards. Confirm availability through authorized distributors as stock levels vary.

Selection Notes

Select this component when a single-channel, low-cost isolation solution with NPN output is required. Consider the 3750 Vrms isolation rating for safety requirements. Verify that the SOP-8 package fits your PCB layout constraints and that the transistor output type matches your circuit design needs.

Part Context

This part belongs to Everlight's general-purpose optocoupler family. It is distinct from dual-channel variants like the ELD205 series. The TA suffix typically denotes specific packaging or tape-and-reel configuration details defined by the manufacturer.
