Overview
The EL852(S)(TU)(D)-V is a single-channel optoisolator featuring a Darlington phototransistor output. It provides high isolation voltage of 5000 Vrms between input and output circuits. The device operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter saturation voltage of 1.2V, a typical rise time of 300µs, and a fall time of 100µs. The output channel supports a current capacity of 150mA. The component is housed in a 4-SMD gull wing package.
Feature Summary
- Darlington output configuration for high current gain
- High isolation voltage capability of 5000 Vrms
- Extended operating temperature range from -55°C to 100°C
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify the specific suffix codes against official Everlight documentation to confirm package type and tape/reel specifications. Ensure the requested variant matches the required isolation voltage and output current ratings for the target application. Cross-reference part numbers with manufacturer datasheets to avoid substitution errors due to minor packaging differences.
Selection Notes
Select this component when high current transfer ratio is needed via Darlington output. Verify that the 150mA output current meets load requirements. Confirm that the 5000 Vrms isolation rating satisfies safety standards for the intended circuit. Check thermal management needs given the 100°C upper operating limit.
Part Context
This part belongs to the EL852 series of optocouplers manufactured by Everlight Electronics. The series typically offers transistor or Darlington outputs for general-purpose isolation applications. The specific model indicates surface mount packaging with defined electrical characteristics suitable for compact designs.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 5000 Vrms isolation and Darlington output type. Verify pinout compatibility and package dimensions before integration.
