Component

Darlington optocouplerPhototransistor output5000 Vrms isolation350 V VCEOHigh CTR4-pin family

EL852S is an AOTE Darlington optocoupler listed as a phototransistor-output device. The supplied EL852 family datasheet specifies 5000 Vrms isolation, 350 V VCEO, and 1000% to 7500% CTR.

Best for

  • Low-speed isolated control signals
  • Relay and PLC interfaces
  • Power-supply feedback isolation

Avoid if

  • High-speed digital isolation
  • Applications requiring tightly controlled CTR without device-level validation
  • Designs where the exact package variant is not confirmed

Check before use

  • Confirm EL852S package and pin-compatible mechanical drawing
  • Design using worst-case CTR rather than typical behavior
  • Verify output switching time against system timing requirements
