Overview
The EL814S(A)(TU) is a single-channel transistor-output optoisolator manufactured by Everlight Electronics. It features an AC input configuration utilizing 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 the input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 80 V, a typical forward voltage (VF) of 1.2 V, and a maximum forward current (IF) of 60 mA. The current transfer ratio (CTR) ranges from 50% to 150%. The component operates within a temperature range of -55°C to 110°C and is housed in a surface-mount 4-pin package.
Feature Summary
- AC input response capability enabled by dual inverse-parallel infrared LEDs
- High isolation voltage rating for reliable signal separation
- Wide operating temperature range suitable for demanding environments
Applications
- Signal isolation in AC-powered control circuits
- Interface between microcontrollers and AC loads
- Noise immunity in industrial communication systems
Procurement Notes
Verify the specific suffix designation against the manufacturer's latest documentation to confirm pinout compatibility and compliance status. Ensure that the surface-mount package dimensions match the intended PCB layout constraints. Confirm that the thermal management strategy supports the specified operating temperature range during continuous operation.
Selection Notes
Select this component when AC input detection is required without external rectification circuitry. The dual-diode input structure simplifies design for alternating current signals. Consider the CTR tolerance and isolation voltage requirements relative to the system's safety standards. Evaluate the surface-mount form factor for automated assembly processes.
Part Context
This part belongs to the EL814 series, which includes various packaging options such as DIP and SMD configurations. The series is designed for general-purpose optocoupling applications requiring AC input functionality. Other variants in the family may differ in package type or specific electrical tolerances while maintaining the core AC input feature set.
Replacement Considerations
Direct substitutes must maintain the AC input architecture with inverse-parallel LEDs. Verify equivalent isolation voltage ratings and package footprint compatibility. Cross-reference with other manufacturers offering similar AC-input transistor output optocouplers in a 4-pin SMD format.
