EL814S1(TA)

Overview

The EL814S1(TA) is a single-channel optocoupler featuring an AC/DC input phototransistor output. It integrates two infrared emitting diodes connected in inverse parallel with a phototransistor detector. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.2V, and a maximum DC forward current of 60mA. The device offers high isolation voltage of 5000Vrms and operates within a temperature range of -55°C to 110°C.

Feature Summary

• Features dual inverse-parallel infrared LEDs for AC and DC input compatibility
• Provides high electrical isolation between input and output circuits
• Utilizes a compact surface-mount package design

Applications

• Digital logic signal transmission and conversion
• Power supply control and switching circuits
• Electrical insulation isolation between circuits and systems

Procurement Notes

Verify the specific suffix (TA) against official Everlight documentation to confirm pinout configuration and tape-and-reel specifications. Ensure compliance with RoHS standards as indicated in manufacturer records. Cross-reference datasheet revisions to confirm current manufacturing status and any potential process change notifications affecting performance or packaging.

Selection Notes

Select this component when bidirectional input capability is required for AC or DC signals. The high isolation voltage makes it suitable for safety-critical applications. Verify that the 80V output voltage rating meets the load requirements. Consider the operating temperature range if deployed in extreme environmental conditions.

Part Context

This part belongs to the EL814 series of transistor-output optocouplers manufactured by Everlight Electronics. The series is designed for general-purpose isolation applications. The TA suffix typically denotes a specific package variant, often associated with DIP or SMD configurations depending on the specific datasheet revision.

Replacement Considerations

Check for direct substitutes such as the EL814S1(A)(TB)-V or similar variants within the EL814 family. Ensure pin compatibility and identical isolation ratings before substitution.
