Overview
The EL827S(TB)-V is a dual-channel transistor output optocoupler manufactured by Everlight Electronics. It features an NPN phototransistor output and provides 5000 Vrms insulation voltage for signal isolation. The component is designed for surface mount applications in an 8-SMD, Gull Wing package. Key electrical characteristics include a maximum collector-emitter voltage of 80 V and a maximum collector current of 50 mA. The device operates within a temperature range of -55°C to +110°C and supports a DC forward current up to 60 mA.
Feature Summary
- Dual-channel configuration for simultaneous signal isolation
- High insulation voltage rating for safety separation
- NPN phototransistor output stage
- Surface mount packaging for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between isolated circuits
- Power supply feedback loops
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix (TB-V) against the manufacturer's latest datasheet to confirm pinout and packaging details. Confirm RoHS compliance status through official documentation. Check for obsolescence or lifecycle changes directly with Everlight Electronics. Ensure the supplier provides valid traceability documents. Validate that the component matches the required surface mount specifications for your PCB design.
Selection Notes
Select this component when dual-channel isolation is required in a compact surface mount form factor. Ensure the circuit design accommodates the 80 V collector-emitter voltage limit. Verify that the input forward current requirements do not exceed the 60 mA maximum. Consider the operating temperature range if the application involves extreme environmental conditions. Confirm compatibility with the target PCB footprint for the 8-SMD Gull Wing package.
Part Context
This part belongs to the EL827 series of transistor output optocouplers from Everlight Electronics. The series offers various channel configurations and packaging options. The EL827S(TB)-V specifically denotes the dual-channel variant with surface mount gull-wing leads. Other variants in the family may differ in channel count, lead style, or insulation ratings.
Replacement Considerations
Consult Everlight's official substitution guide for verified alternatives. Cross-reference pinouts and electrical parameters with potential substitutes. Ensure any replacement maintains the 5000 Vrms insulation requirement. Verify package compatibility before implementation.
