Overview
The EL814S1(TB) is a single-channel optocoupler featuring an AC/DC input type with a surface mount SMD4 package. It provides high isolation voltage of 5000Vrms between input and output. The device exhibits a current transfer ratio ranging from 20% to 300% at IF = ±1mA and VCE = 5V. Key electrical parameters include a typical forward voltage of 1.2V, maximum DC forward current of 60 mA, and maximum output voltage of 80V. The operating temperature range spans from -55°C to 110°C.
Feature Summary
- AC input response capability for versatile signal coupling
- High isolation voltage ensuring safety between circuits
- Wide operating temperature range for harsh environments
Applications
- Digital logic transmission and conversion
- Power control and switching circuits
- Electrical insulation isolation between systems
Procurement Notes
Verify the specific suffix (TB) against the manufacturer's latest datasheet to confirm package dimensions and tape/reel specifications. Ensure compliance with RoHS standards as indicated in official documentation. Cross-reference part numbers with Everlight Electronics Co Ltd official records to avoid counterfeit components. Confirm availability status directly with authorized distributors.
Selection Notes
Select this component when AC input compatibility is required alongside high isolation voltage. Consider the SMD4 package for space-constrained PCB designs. Evaluate the CTR range suitability for the specific load requirements. Verify thermal management needs within the specified operating temperature range.
Part Context
This device belongs to the EL814 series, which consists of infrared emitting diodes optically coupled to phototransistor detectors. The series is designed for general-purpose isolation applications. Variants like EL814S1(A)(TU) share similar electrical characteristics but differ in packaging or reel specifications.
Replacement Considerations
Check for direct substitutes such as EL814S1ATB or EL814S1TA from Everlight. Verify pinout compatibility and electrical parameter equivalence before substitution.
