Component

ULN2003Darlington array7-channel driverlow-side driverrelay driverinductive load

ULN2003-DW is a seven-channel Darlington low-side driver for relays, LEDs and other loads requiring current sinking. It supports up to 40 V outputs and 500 mA peak per channel.

Best for

  • Logic-controlled relay coils
  • LED and indicator load sinking
  • Stepper motor and inductive-load interfaces

Avoid if

  • Applications requiring low output voltage drop at high current
  • Designs needing confirmed automotive, RoHS or REACH status from supplied evidence
  • PCB designs where the package footprint has not been confirmed

Check before use

  • Confirm exact package variant
  • Check per-channel and total current
  • Calculate thermal dissipation using output saturation voltage
  • Use COM correctly for inductive-load clamp diodes
