Overview
The EL814S1(A)(TU) is a single-channel optocoupler featuring an AC/DC input type and NPN phototransistor output. It provides 5000Vrms isolation voltage with a maximum output voltage of 80V. The device operates within a temperature range of -55°C to 110°C, supports a maximum forward current of 60mA, and has a typical forward voltage of 1.2V.
Feature Summary
- Features inverse parallel infrared emitting diodes for AC input response capability
- Provides high isolation voltage between input and output circuits
- Offers wide operating temperature range suitable for industrial environments
Applications
- Digital logic transmission and conversion
- Power control and switching circuits
- Electrical insulation isolation between circuits and systems
Procurement Notes
Verify the specific suffix (TU) against the manufacturer's latest datasheet to confirm surface mount package dimensions and tape-and-reel specifications. Ensure compliance with RoHS standards and check for UL or VDE approvals required by your target market regulations before finalizing procurement.
Selection Notes
Select this component when AC signal detection is required alongside standard DC isolation. The dual-diode input structure enables bidirectional current flow, distinguishing it from standard single-diode optocouplers. Verify that the 80V collector-emitter breakdown voltage meets the load requirements of the isolated side circuitry.
Part Context
This part belongs to the EL814 series, which utilizes two infrared LEDs connected in inverse parallel coupled to a phototransistor detector. The series is designed for compact applications requiring reliable electrical isolation in both AC and DC signal environments.
Replacement Considerations
Check for direct equivalents such as EL814S1(TU) or EL814S1A(TU). Verify pinout compatibility and CTR ranges before substitution.
FAQ
Can the EL814S1(A)(TU) handle AC signals?
Yes, the internal inverse parallel LED configuration allows it to respond to both AC and DC input signals.
What is the maximum isolation voltage?
The device supports an isolation voltage of 5000Vrms between the input and output sections.
