Overview
The EL814M(A) is a single-channel optoisolator featuring an AC/DC input phototransistor output. It utilizes two infrared emitting diodes connected in inverse parallel, optically coupled to a phototransistor detector. The device provides high isolation voltage of 5000 Vrms and operates within a wide temperature range of -55°C to 110°C. Key electrical parameters include a minimum current transfer ratio (CTR) of 20% at ±1mA input with 5V collector-emitter voltage, a maximum CTR of 300%, and a collector-emitter breakdown voltage of 80V. It is housed in a compact 4-pin DIP package.
Feature Summary
- AC input response capability due to dual inverse-parallel infrared LEDs
- High isolation voltage between input and output terminals
- Wide operating temperature range suitable for harsh environments
- Compact dual-in-line package design
Applications
- Signal isolation in AC-powered control circuits
- Interface between microcontrollers and AC loads
- Noise immunity in industrial communication systems
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix codes (e.g., M, A, TA, TB, TD, VF) against the manufacturer's datasheet to ensure correct packaging, lead time, and compliance status. Confirm RoHS and UL/VDE recognition requirements match your application standards. Check for active production status as some variants may be discontinued or have limited availability.
Selection Notes
Select this component when AC input detection is required without external rectification. Ensure the 80V collector-emitter voltage rating exceeds the load voltage. Verify that the 5000 Vrms isolation meets safety regulations. Consider the 20% minimum CTR for logic level compatibility. Compare pinout and package dimensions with existing PCB footprints before finalizing the design.
Part Context
The EL814 series belongs to Everlight's family of 4-pin DIP phototransistor optocouplers. These devices are designed for general-purpose isolation applications where AC input compatibility is beneficial. The series includes various packaging options such as through-hole DIP and surface mount variants, catering to different assembly requirements while maintaining consistent electrical performance characteristics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official cross-reference guide for equivalent components.
