Overview
The EL814S1(A)(TA)-V is a single-channel optocoupler featuring an AC/DC input phototransistor output. It integrates two infrared emitting diodes connected in inverse parallel with a phototransistor detector. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a typical forward voltage of 1.2 V, and a maximum DC forward current of 60 mA. The device provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to 110°C.
Feature Summary
- Features dual inverse-parallel infrared LEDs for AC input capability
- Provides high isolation voltage between input and output circuits
- Offers wide operating temperature range for extreme conditions
Applications
- Digital logic transmission and conversion
- Power supply control and switching
- Electrical insulation isolation between circuits
- Impedance transformation between systems
Procurement Notes
Verify the specific suffix TA indicates the tape and reel packaging format when ordering. Confirm RoHS compliance status as required by project specifications. Ensure the supplier provides official datasheets matching the exact part number to guarantee correct pinout and electrical characteristics. Check for any regional distribution restrictions before finalizing procurement plans.
Selection Notes
Select this component when AC signal detection is required at the input stage without external rectification. The dual-diode configuration simplifies circuit design compared to standard DC-input optocouplers. Consider the 80 V output voltage rating for low-voltage logic interfacing. Verify that the 5000 Vrms isolation meets safety standards for the intended application environment.
Part Context
This device belongs to the EL814 series manufactured by Everlight Electronics. The series utilizes a compact surface-mount package suitable for automated assembly. It serves as a cost-effective solution for galvanic isolation in industrial and consumer electronics applications requiring reliable signal transfer across isolated boundaries.
Replacement Considerations
Equivalent parts include EL814S1(A)(TB)-V and EL814S1(TA)-V from the same manufacturer family. Cross-reference pinouts and packaging dimensions to ensure mechanical compatibility. Verify that alternative components meet the same isolation voltage and CTR requirements.
