Overview
The EL814(A) is a single-channel optocoupler from Everlight Electronics, featuring an AC input configuration. It integrates two infrared emitting diodes connected in inverse parallel with a phototransistor detector. The device provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter voltage of 80 V. It operates within a temperature range of -55°C to 110°C, with a typical forward voltage of 1.2 V and a maximum forward current of 60 mA.
Feature Summary
- AC input response capability via dual inverse-parallel infrared diodes
- High isolation voltage between input and output circuits
- Wide operating temperature range suitable for industrial environments
Applications
- AC signal switching applications
- Industrial control systems requiring galvanic isolation
- Microcontroller interface circuits for AC sources
Procurement Notes
Verify the specific suffix designation (e.g., A, TU, TB) against the manufacturer's datasheet to ensure correct packaging and compliance status. Confirm RoHS and lead-free requirements match project specifications. Check for active production status or obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when AC input detection is required without external rectification. Ensure the circuit design accommodates the inverse-parallel diode structure. Verify that the required isolation voltage meets system safety standards. Consider the package type availability for PCB layout constraints.
Part Context
The EL814 belongs to the EL814 series of 4-pin DIP phototransistor optocouplers. This series is designed for applications requiring reliable isolation between low-voltage control circuits and higher-voltage AC loads. The standard DIP-4 package facilitates through-hole mounting.
Replacement Considerations
Cross-reference with other AC-input optocouplers offering similar isolation voltages and CTR ranges. Verify pinout compatibility and electrical characteristics such as rise/fall times and saturation voltage before substitution.
