Overview
The EL814S(A)(TB)-V is a single-channel AC input-transistor output optocoupler manufactured by Everlight Electronics. It features two infrared emitting diodes connected in inverse parallel, optically coupled to an NPN phototransistor detector. The device provides high isolation voltage of 5000 Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter breakdown voltage (VCEO) of 80 V, a typical forward voltage (VF) of 1.2 V, and a maximum continuous forward current (IF) of 60 mA. The component operates within a wide temperature range from -55°C to +110°C and has a power dissipation rating of 200 mW.
Feature Summary
- AC input response capability due to dual inverse-parallel infrared LEDs
- High isolation voltage of 5000 Vrms between input and output
- Wide operating temperature range suitable for industrial environments
- Compact surface mount package design
Applications
- Solid-state relay driver circuits
- Microcontroller interface isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify the specific suffix codes against the manufacturer's latest datasheet to ensure compatibility with required certifications such as UL or VDE. Confirm that the surface mount package dimensions match the target PCB footprint. Check for RoHS compliance status if restricted substances are a constraint. Ensure the ordering part number matches the exact tape and reel specifications needed for automated assembly processes.
Selection Notes
Select this component when AC signal detection or bidirectional LED driving is required without external rectification. The high isolation voltage makes it suitable for mains-connected applications. Consider the 80 V collector-emitter voltage limit for load switching requirements. Verify that the surface mount form factor aligns with manufacturing capabilities compared to through-hole alternatives like the standard DIP version.
Part Context
This device belongs to the EL814 series of optocouplers, which are designed for general-purpose isolation applications. The series typically includes both through-hole DIP and surface mount variants. The 'S' in the model indicates a surface mount package, while '(TB)' denotes specific packaging or tape-and-reel configuration. This family is widely used in industrial control and consumer electronics for galvanic isolation.
Replacement Considerations
Direct substitutes may include other AC-input transistor-output optocouplers with similar isolation ratings. Verify pinout compatibility and package dimensions before substitution. Cross-reference with LTV-814S series devices from Lite-On, ensuring electrical parameters such as CTR and VCEO meet circuit requirements.
