AT3H7D-CUH-S

Component

phototransistor optocouplerSSOP-43750 Vrms isolation80 V outputD CTR bin

AT3H7D-CuH-S is a 4-pin SSOP phototransistor optocoupler for isolated low-speed control and signal interfaces, with 3750 Vrms isolation and an 80 V output transistor.

Best for

  • PLC and sensor-interface isolation
  • Industrial control inputs and outputs
  • Power-supply feedback or status isolation

Avoid if

  • High-speed digital isolation is required
  • Guaranteed CTR outside the stated bin and test conditions is needed
  • The design requires an isolation rating not validated by this datasheet

Check before use

  • Confirm the actual CTR bin on procurement documentation
  • Verify output load resistance and switching response
  • Review PCB creepage and clearance for the application voltage
