Overview
The EL1110(TB) is a single-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output with a base terminal, housed in a 5-pin Long Creepage Small Outline Package (SOP). The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. It is designed for applications requiring signal transmission between isolated circuits while maintaining high voltage withstand capabilities.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor featuring a base pin for improved switching performance and controllability.
- Utilizes a long creepage distance SOP package design to enhance high-voltage isolation reliability and safety compliance.
- Provides galvanic isolation between input and output circuits to protect sensitive components from voltage spikes.
Applications
- Industrial control systems requiring isolated signal interfaces
- Computer peripheral interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation on the component marking against the official datasheet to confirm package type and lead configuration. Ensure that the procurement source provides valid traceability documentation. Confirm RoHS compliance status as per the latest manufacturer revision notes before integration into production.
Selection Notes
Select this component when a phototransistor output with a base terminal is required for faster switching or linear operation compared to standard variants. Consider the 5000 Vrms isolation rating for high-noise environments. Verify that the SOP footprint matches the PCB layout constraints and thermal management requirements of the target application.
Part Context
This part belongs to Everlight's family of transistor output optocouplers designed for general-purpose isolation. The EL1110 series specifically addresses applications needing reliable signal transfer across isolation barriers. The long creepage SOP variant offers enhanced safety margins over standard packages in high-voltage scenarios.
Replacement Considerations
Consult official cross-reference lists for direct replacements. Verify pinout compatibility and electrical parameters such as CTR and isolation voltage before substituting with other manufacturers' equivalents.
